Evoc are a good shout just depends on how big a back you want. I have the FR Tour for family rides out so I can take the kitchen sink with me in terms of 4 different tube sizes, spare clothes for the kids and assorted snacks and drinks.
Suspect it would be a good bag for very long rides but aside from the family rides it’s my commuter bag, laptop work clothes etc.
My normal riding pack is the FR Blackline, essentially the 20l bag. I could get away with a smaller bag for most of my riding but occasionally it gets used for big days out… not happened this year 🙁
I think all the evocs with back protectors have straps for armour and can carry lids. You just need to work out how much stuff you normally carry.
