The best AFK server you'll find is one you setup yourself using the latest PEQ Build available on Emu. You can set your own server up. That will be live equivalent through Omens. The client is RoF2 if you use it, but that doesn't include NPC data or everything through ROF. That's built through the database which is what they are working on with PEQ. It's moving to DoN next. You can make your own tweaks to NPC strength, drop rates, whatever, to make this fit what you're looking for. If you're feeling ambitious you can create your own spawns and such, or even thematically change a zone. Example, an old emu server I used to help with I turned Plane of Growth into a half half faction war between followers of Tunare and Innoruuk. There's a lot you can edit with the database so you're really only limited by your creativity (and time, and interest in learning).
One thing to note with Emu is the popular flavor of MQ2 is the E3 variant. Many of these servers will have discussions and resources surrounding E3 usage and in my experience users with CWTN or Kiss are rare. E3 is a great alternative and makes sense, but requires some massaging of ini files and is not as load and play as RG is.
I've tried most of these servers.
Enine's - Fun custom server, 6 box is effectively what you'd want to get the most out of it.
Lazarus - Omens legit, kind of. This server allows a lot of out of era spells and AA and has some custom ones. Decap, for example, is available even though the cap isn't 80s. It's a buff that adds a big proc. Content tuned for 2-3 groups in raids. So this is a great option for seeing through Omens with 6 with some added player power. It is free trade but gear past Luclin is attunable. This is probably the best middle ground between legit and custom by emulating a live like environment with plenty of QoL. If you're into the Omens lock this would be if you don't mind some customization. MQ2 is fine except AFK.
Dark Exile - Kind of an 8 Box TLP, you're progression locked through GoD. This is a challenging server and will take some time. It's got some QoL, but not as customized. MQ is fine.
EZ Server - Very heavily customized, this is not relatable to live. But is fun on its own right. MQ2 is a necessity on this server but it does have restrictions. No AFK, Warp etc. GM is active and they do monitor exploits. Solid community. Server is very grind oriented and if you're a spreadsheet and grind person this is the server you want. 12-18 boxing is honestly a must if you want to effectively progress past the middle tiers, in my opinion.
Hidden Forest - Heavily customized, and has some fun raid tiers. MQ is allowed, but no AFK or Warp. This server is great if you want to hit some nostalgic targets then move into more customized content later. T8+ breaks the mold of using old EQ raids and introduces more unique things to this server. Most of the zones used are PoP or lower. This server is somewhat pay to win as it has an extensive donor system that can really adjust your player power and QoL. If you want to box heavy and see custom content don't let the stagnancy or the population dissuade you. It's fun to work through for the first time and it will all be new to you.
Imperium - 2 Box, no MQ (you don't need it). Tuned for two, lots of custom content. Has bots (emu version of mercs, requires a bit of a learning curve). Fun to work through the content here and has a good community. IS Boxer is fine. The 2 box limit is IP enforced similar to truebox on live.
Shards - Heavy custom, no MQ, very toned down version of the game in terms of stats and numbers. Introduces a lot of its own systems that hold up decently. Has leaderboards. Just started doing seasonal content, which really just translates to it's iteration of the live TLP relating to their content.
Dreadbox - Boxable (maybe an IP limit) but doable solo. MQ fine, allows warp even. Can do this server with some classes without boxing at all. Heavy custom server and still releasing new tiers. Easy to work through quickly.
Plenty of others. But just providing some additional to a few on your list that I can think of off the top of my head.
Edits - Lots of typos, autocorrects from phone.
