Possible remedies -

Heat shield, or better heat shield for starter.

Maybe your starter is a little weak, possible replacement

3rd gens actually got a little fan to blow on carbs after shut off. They boiled fuel and ran bad. Little fan from factory was created to cool and prevent hot-soak, it went on when key was off.

Bigger battery - not likely to fix it
I think you are right. I experience similar issues. I haven't got to the point where it wouldn't crank at all but I notice on cold start the starter turns over strong and fast but if I am running errands and have to keep stopping for short periods with a few frequent startups the starter will feel sluggish to turn over. However, like you mentioned if I let it sit for a while and cool it will cranks over fast. Battery is good.
