I used this 20 pack. Cards fit in sleeves, but it’s a tight fit sleeved.
Amazon link to card holder sheets for smaller cards. Sleeved cards fit just fine in these.

Putting them in a binder lets you more easily find a specific card they fit in these sheets even with card sleeves. The CD case holds any tile 4 spaces wide I keep the larger tiles separate and was able to fit every expansion in the CD case.
Here you go! This is more than enough for gloomhaven and maybe frosthaven in the future. Amazon
Also one thing I forgot to mention is that sleeping player cards and attack modifiers is pretty important is me you use them so much and they wear easy. It’s not important in JOTL since your character never retires and you play it to completion, however, in Gloomhaven there are basic attack modifiers that you use and then add character cards so you use the same deck for every character and they can wear fast. Also o sleeved the enemy decks as well. I bought 100 standard 2.5” by 3.5” and that is more than enough. I also bought 400 mini European sleeves (I believe it was 400, could be 450) and I have some left over. 400 is safe since there are 236 monster attack decks and multiple attack modifiers decks.
Not as good of quality but these are what I'm using: https://www.amazon.com/gp/aw/d/B018OM5MGC/ref=mp_s_a_1_1?ie=UTF8&qid=1502164999&sr=8-1&pi=AC_SX236_SY340_FMwebp_QL65&keywords=bcw+pro+16-pocket+page+-+topload+-+%2820+ct.+pack&dpPl=1&dpID=41QnoY4xaIL&ref=plSrch
