When we did our bathroom over - I insisted on a higher vanity - DH kicked and screamed every inch of the way -
We bought a small RV in Florida, and the vanity was "standard" low height - he raised it several inches!
Maybe start with your kitchen counters as a benchmark for a comfortable height and adjust that height for you.
I agree that "regular" table height is much too low for cutting for a very long time.
Interestingly enough - I can sit on the couch and use the coffee table for "trimming" for quite a while before I get miserable.
