Upgrading from a hybrid — looking for my first endurance road bike

Hey everyone! I've been riding a hybrid for a while now and I'm ready to make the jump to a proper road bike. My goal is to do longer rides — multi-hour days on city roads, bike paths, and pavements
My noob research tells me to go for a used bike with following specs.

Please give me your valuable insights if I am missing something and which specs should be non-negotiable and which ones I shouldn’t be hell bent on. Also some model names I should look for in particular?

Shimano 105 groupset
11 or 12 speed
50/34 compact crankset
11–34 cassette
Hydraulic disc brakes
