each person, do what you want.

ive made up my mind just like everyone else has.

and extra 1-2 gallons isnt going to make a difference to me, so what if i get any extra 20-40 miles a tank.

in the grand scheme of things, our winters dictate i wont go below 1/3 or 1/2 tank for safety concerns in case i get stuck during cold season and i have to wait 2-3 hrs for a rescue. that reserve is to let me be casual about keeping warm until help arrives.

the wife is even worse, 1/2 tank and it gets filled whether its summer or winter. it drives her nuts if i let it go below 1/2 no matter the vehicle.
Absolutely. At the end of the day you are the one who has to pay for any repairs due to how you fill your vehicle. It's also your limited time on this planet. If filling up more often makes you feel more comfortable then that's what you should do. It's the same with what weight oil to use. or if you remove the tag from your mattress.

I always try to fill the tank up so I can see fuel after I'm done filling the tank. I've logged close to a million miles now doing so. Maybe I'm lucky, maybe I'm right. But there's the chance that if someone else follows my advice they may not be as fortunate. I have a background in automotive repair (even though never a professional mechanic) with a 2 post lift in my garage. If I have to replace it then I will.

My personal feeling is that evap canisters don't die very often. People replace them because they assume that's the problem. The purge valve is much more likely to be the cause. I have to believe that a garage is going to change both (and make more money) since they both have the same signs when they fail.

I believe this is also happening to me (Limited) because I had less than 50 miles to go when I last filled up and it only added ~ 15gal. The gauge didn't look like it was totally filled. I told myself I would really pay attention the next time. But if this is a thing, why? It seems you should be able to fill a 19gal tank with 19gal without concern for the evap.
Is it your Toyota or the gas station fill nozzle that's wrong? Nevertheless, you have to be careful to not overfill with pressure. It can damage you evap stuff, according to the Owner's Manual.
