When I was messing about with saddle height trying to see if it made any difference to power (it didn't), I'd set it up / down and then ride hard for 15-20 minutes to see how I felt. Raising it a centimeter up from my normal position, I could feel discomfort in the groin starting to build up after 20 minutes; higher saddle generally equals higher saddle pressure. The same saddle, I can spend hours on end on it in a trisuit with minimal padding and feel just fine.

I'd revisit basic fit coordinates if I felt groin pain then check if the saddle is wide enough to support the sit bones.

Personally, I'm a fan of short nosed saddles with a cutout but that's more of a personal preference, and I've tried a few longer saddles which were fine as well. As for saddle angle, saddle level was a rule for the longest time and UCI rules tend to shape the way road bikes are made and the way people fit and ride them. That was only dropped a couple of years ago, so I wouldn't put much stock in "saddle level is how it was always done". For me,saddle angled down and short-ish cranks enable me to ride in the drops for as long as I like without being uncomfortable in any way despite a very significant saddle to bar drop (about 12 cm or so). I could live with a level saddle, but this does create more room for my dangly bits.
