Help needed

Hello to everyone. I've been looking for a bag to buy lately and the idea of a hybrid one also for my photography equipment seems rly nice. I don't want to take all my equipment with me in my trips just a camera with a lens and maybe a drone. The rest will be for my clothes etc. So I was thinking something like a PGYtech onemo 2 25l (or 35l) or the onemo travel backpack. I hate these extra cubes but the backpack looks rly cool. Are all the options carry on? Are there any other better options? Am I asking too much? Maybe a classic backpack for traveling and an other one smaller for my photography equipment would be wiser? What do you think? I want to focus that I will be using the backpack to be able to carry my camera and drone to my trips. Thank you all in advance!
