On my last trip to Ireland I had the 23/1.4 on 90% of the time. Just had a week in Thailand and the 18/2 was the only lens I used on that trip. I take family shots, landscapes and street photos usually on my trips if that helps.
If you are not afraid to actually 'move about' then stick to a small selection of primes.
The pancake is giving you 40mm FOV in full frame language and works brilliantly indoors/quits and street stuff. Its best kept on your camera covering those unexpected snatched captures.
The 16/50 is not a lens that I kept for long.
The 10/24 is my go to countryside lens (cannot afore the8/? newline) and I don't actually need anything faster as the tripod is always with me.
The next very useful lens of exceptional quality is the 60mm macro (portraits/macro&sport)
Beyond that you are getting back to the weight problem so to start that would be my starting lineup.
Only piece of advice I can give without any worries about putting you wrong is - take a LOT OF PHOTOGRAPHS - keep notes and cull viciously. This willet you into the "Fuji Mode" of seeing and away from the Cannon. The images will THEN start to look like yours.
