To me, a circular saw has always been 7-1/4" but the cordless tool sets sometimes offer saws with smaller blades. How difficult is it go find their sizes? 6-1/2 inch? 5 inch?

Any box store caries multiple blades in those sizes.

I can't find fine tooth blades for my little Dewalt cordless in the big box stores. Amazon and many other online suppliers have them though. I can't even remember the size off the top of my head, but it's oddball with a small arbor.

Ha I have a 7 1/2" Craftsman too!
A radial arm miter saw. There are still blades that size out to found out there but not many. Makita has some.
Without building the table up I have found a few 7 1/4" blades will just make it but others wont and some are also sized for 7" saw.
OP...I think I have had 6 1/2" and 5 3/8" saws for at least 20 years never any problem finding blades in those sizes

You can buy just about any size but finding the vintage 9 inch blades tends to be somewhat harder (think vintage and not modern), and then Ebay is your friend.
My dad gave me a Craftsman table saw, 9", circa 1970. I was able to order blades through carbide.com. I finally sold it in favor of a Ridgid 10". Over time, the lower price of the sawblades will offset the purchase price of the new saw. I don't have a need or use for high end blades - I'm not building fine furniture, so I use standard, readily-available blades.

Cordless circular saws have smaller blades because the motors do not have the same power as corded circular saws. Corded circular saws have smaller blades than table saws for the same reason. Blade size is based on the balance between capability, motor power and portability. In the early days of cordless circular saws the blades were limited to 4-5" and now that battery technology and motor power have improved, the saws can drive 6 1/2" and 7 1/4" blades.
I think it was 4" or 4-1/2" trim saws that came with the 19.2v craftsman? Most other cordless circ saws are 6-1/2" blades. They are designed to go through soft framing lumber. not intended for much trim work but I have seen it done. So they weren't designed originally to need fine tooth blades. 18-24 is typical.
You can probably find higher tooth counts nowadays. I would imagine it's much harder on batteries cutting harder woods or trying to make finer cuts with a higher tooth blade than what they were intended. The motor can probably do it but as it stands most of the cordless circ saws are not new designs and aren't as efficient, so their pull on the battery is going to be much harder than basically any other tool besides maybe an angle grinder.
If you have a saw already and have a need for it I would stick with the rougher cut blades unless the portability is a major factor for you. It might be, up a ladder weight and cords are equally concerning.
If you don't have a saw and are looking for one get the M18 fuel as they make one for 7-1/4" blades. Still don't know if I would cut hard materials with it though.

I have an old Skil worm drive circular saw that takes 8-1/4" blades with diamond knockout, the blades for that were a little harder to find, only one of the box stores had one in stock and it was $$$. I had better luck on ebay.

I still have one of those somewhere, without the track. Those were the **** 20-25 years ago. Remember the metal box they came in? I might have to go look for it.
My Milwaukee worm drive is still my favorite even though it's only 7 1/4. I call it "The Big Dog".
I have a Dewalt 6 1/2" and Ryobi 5 1/2"cordless models. I actually use the Ryobi a lot because the small blade has such a narrow kerf that it cuts almost effortless. This extends battery time by a ton.
