I list only on .ca, my items are available worldwide and show up on all other eBay sites.
Which site you open your store on really makes no difference.
The "visibility" fee is a crock, the only reason it still exists is to sucker a few more fees. Basically that feature was introduced about 10 years ago and was then promptly abandoned. If you read the help page on ISV the wording has remained unchanged in all these years, it talks about expanding to other sites beyond the UK, this NEVER happened.
Just list your items on .ca or .com, indicate you ship worldwide and provide a shipping rate for worldwide.
My overseas sales are down considerably from where they used to be but that has nothing to do with where they are listed and everything to do with the huge rise in value of the US Dollar relative to other currencies (especially the Pound & Euro). If you list in Canadian Dollars the impact has been less but it's still had a negative impact.
Soon, I intend to start using a freight forwarder that ships from outside of Canada, as Canada Post rates are insanely high, and thus would not be shipping from Canada and UK.
Your items are still located in Canada so how you are shipping isn't relevant to anything other than your wallet.
Item location: Langley, BC, Canada
Shipping to: Canada, United States, France, Australia, United Kingdom, Germany
Why the odd selection of countries you ship to? If France & Germany are OK why not the rest of Europe?

I just went to ebay.co.uk, and did not log in.
I searched for "raspberry pi robot", none of my Raspberry Pi robot controller results showed up.
I searched for "raspberry pi robot controller", my results showed up at the bottom, as international seller
"raspberry pi prototyping", none of my boards showed up at all
This is a concern as most Raspberry Pi's were sold in the UK and EU, and I truly hate the $0.10-$0.40 "sucker fees"
On .uk if you select Worldwide on the left your items do show up.
In theory if you pay extra for ISV your listing would show up without needing to tick the Worldwide box. Balance that with the fact that some portion of UK buyers will always be selecting Worldwide because without it they simply don't find much to buy.
One additional factor to consider, if you list directly on sites other than .ca/.com those listings fall under all the rules of that local site, the rules and policies on other eBay local sites vary quite a bit from the policies for .ca/.com, the complications may outweigh the benefits.
That said there are plenty of sellers who list on many eBay sites, .uk is especially popular with Asian sellers.
"I may open a regular seller account on Ebay.co.uk and list just auctions there."
There is no advantage in opening a second eBay seller account.
The one account you have allows you to list anywhere in the world in local currency (US$ on eBay.com, Cdn$ on eBay.ca, £ on eBay.uk, € on eBay.fr or eBay.de. etc....)
Having one User ID also allows all feedback to build under one account.
While I have listed on eBay.uk (in Sterling) from time to time when I had products of specific interest to UK buyers, I find that buyers from anywhere will find my listings by offering "worldwide shipping".
No, I do not waste money on that international visibility option.
As far as having a store is concerned, opening the store on eBay.ca has a small advantage at this time as the monthly fee is Cdn$ 19.95 while the fee on eBay.com is US$ 19.95 (a difference of about $4 a month at current exchange rate). It does not matter where you list (eBay.ca or eBay.com or any other eBay sites) nor the currency you use to list or your billing currency. The saving is yours.
"This listing is for a SchoolBoard KIT only (see Photo#2), and does not include any of the other items shown for illustration purposes.
(DOES NOT INCLUDE: assembly & testing, Parallax QuickStart, Raspberry Pi or Pi Jumper - only items shown in Photo#2"
Really? Pictures showing what they are not going to get? eBay's position is that you only show what the customer is getting and in the condition they are getting it.
Buyers do NOT read.
Buyers go strictly on pictures. Do not show extra parts. Do not show the completed kit. They will expect the extra parts and they will expect it assembled.
It is not an auction, it is a BIN.
eBay offers two formats for sellers wishing to list on their site:
Fixed price format - also known as BIN (Buy-it-Now) - seller decides the price
Auction format where the item is sold to the highest bidder. - buyer decides the price
Now, some sellers will list an item at auction with a Buy-it-Now option (must be 30% higher than auction starting price)
Du fragst dich doch selber, was denn ein Kugelschreiber ist?
OR MAYBE BETTER:
Wonder, what a KUGELSCHREIBER is? 
EXACTLY FOR THAT REASON items listed on German (or French) Ebay website CANNOT appear on EVERY Ebay website around the world.
Sorry 38e_avenue, you are incorrect (that sound better than "plain wrong").
Take a look at this search result page from eBay.fr (France) for "Saskatchewan Law stamps NH" :
You will find many listings from Canadian sellers offering to ship worldwide.
The French, and German, and Italian, and Spanish buyers do find my listings and buy from me.
I had a purchase tonight from the Maldives (Indian Ocean)!
The world is your oyster... if you know how to use the system.
Not exactly. it happened EXACTLY what I predicted:
0 résultats trouvés pour Saskatchewan Law stamps NH
Which means in English: "0 results found"
Below that appears "6 objets trouvés disponibles auprès de vendeurs eBay internationaux", which means "6 items found offered by international sellers".
Please re-read my post.
And if you will do the same on German Ebay, you will get 0 results, even without links to you listings at all.
