@CBandAmp-F0 at the beginning of hosting I've done the research. Listings with perfect 5,0 ratings were new, with just a few reviews. Sooner or later some guests will give 4* for some reason including the "nobody is perfect" one. You can't be everything to everyone all the time and turn yourself into a doormat bc you will burn out.
The most important is to examine the demand and the type of guests in your area and to find a balance between how much you earn, how much you work, how much time you spend, and what the major part of your guests' need. For example, if you live in a transit town, the average stay is 1-2 nights then there is no need to offer a washer and dryer or an oven... especially if there is a laundromat and numerous restaurants nearby. It would cost you money, time, and work and it would mean nothing to your guests.
Even the superhost badge doesn't mean much these days, for example, I've lost mine bc I couldn't host for a year due to the earthquake damage on our building's chimney and some other hosts lost it bc there were no tourists due to covid.
Every host with a rating between 4,5 and 5* is a great host and every host who hosts more than a year or two is making some profit out of it.
