My Galaxy S21 lets me pick between normal, fast, or super-fast charging in the settings. Not quite one tap, but it does let you do it.
That said "super-fast" charging on it is like 18W and still about an hour from 20%, so it doesn't really qualify as fast charging IMO, and at an hour is certainly not going to be causing any excess battery wear. It's just normal speed.
For sure, but for terms of battery wear all that really matters is the time to charge. Under 1 hour is getting into the realm of 'really fast' and heat inside the cell starts to become an issue.
