My wife is a degreed horticulturist. You sound pretty much like her. She is very selective on who will treat our lawn and also selective on how she will let them treat it.
Our grass is always high and we use very little herbicide if any. We have about 3/4 acre and we only mess with about 1/2 of it. The other half is pretty much natural except for a few plants she add here and there. Only part of it gets any trimming and that only twice a year.

She managed an estate before she retired.
