"Normal" would probably be about 93% with that cycle count, but you are not far off. Whenever you deal with averages, there will be some that would fall below that mark and others would be above, but that does not mean there is anything wrong with your battery.
For best charging habits, I would recommend to use Optimized Charging and charge your phone all night, every night. Otherwise you may just be wasting charge cycles when the phone is not plugged in and not in use. Also never let it drain completely where it shuts off.

Does it say "Normal" when you go to Settings>Battery>Battery Health. If so, your battery is fine. And as it's highly unlikely that it will drop below 80% before the one-year warranty expires, I don't see much point in worrying about it.
For what it's worth, my iPhone 17 Pro, bought last year on release day, has 356 cycles and 90% capacity. This is the first time I've looked at my battery health in months. The only time it gives useful information is when you're close to the end of the warranty and want to check whether it should be replaced under warranty or if the phone is acting up. Other than that, the information simply isn't actionable.
Mac Jim ID gave great advice on how/when to charge your phone.
