For learning your opener / rotations, I'd definitely check the guides at The Balance. They also have gearing guides (although those are usually focused towards endgame/BiS). There is new gear coming in literally three days though so I wouldn't worry too much about it until the new patch drops, then you can figure out what to get. Generally you will want some mix of capped tomestone (so whatever is purchasable with the new Comedy tomes coming in this patch), and melded crafted gear. Most of the premade gearsets linked on TB and elsewhere will also advise what food to use, and the openers and the like on TB will tell what pots. Again, with a new raid tier coming in literally three days the info is going to change a lot, very quickly, so until then I would focus mostly on learning and practicing your opener and rotation. A big part of endgame raiding is learning how to pull off and coordinate your 2-minute burst and raid buffs, and being able to play your job well is the most important aspect of it. Outside of a few actions you generally won't be using macros or anything automated since those don't accommodate for weaving and other nuances that you'll need to be able to do in Savage.

Unfortunately there isn't a manga, so I'm not exactly sure what you read, but if you are interested in improving you could try - https://www.thebalanceffxiv.com/

You will find the most reliable endgame job guides on https://www.thebalanceffxiv.com/

All the classes have a fairly high level of complexity once you start looking into endgame stuff and a high ceiling for play but some just lose less if you mess up. https://www.thebalanceffxiv.com/ Here is a good site to get started on reading stuff

balance guides are a good starting place

(also there's universalis/marketboard plugin if you wanna check prices quickly, construct is cheapest on lamia right now)

Glad I could help! I've never had much of an issue with selling items, but I also don't play the marketboard like some people enjoy doing. A lot of people use Universalis to compare prices across worlds, especially big ticket items, so if you price things appropriately people will buy them.

So yeah, pay close attention to those tooltips and sites like https://garlandtools.org/ & https://universalis.app/ are great tools for navigating the complicated world of the FF XIV markets!

There are some few custom themed house "skins", which include everything (wall, windows, roof, fence, some garden elements). Note, that they can NOT be customized, and you can't change just walls or just windows. Also, they are pretty expensive, and I'd suggest checking universalis for the best bargain, before buying from your MB (you can travel to other servers from any big aetherite, and local prices are sometimes dramatically cheaper).

Check out Universalis if you spot something on the marketboard that you like. It might be cheaper on another world so you can just hop over there and buy it.

All of this can be done just by normal play for the most part. Outside of that, if I want to make more gil, I set timers on this website for Endwalker Folklore nodes and go gathering for an hour or 2, while gathering from regular nodes inbetween spawns. It helps to check prices on universalis to make sure what your gathering is actually worth it. I also do my weekly Custom Delivereis for crafting and just go to whichever client has a bonus, and turn in the scrips for materia/materials (Immutable Solution usually) and sell that stuff.

You can use Universalis to check prices for fish across your datacenter if the prices are too high or no one is selling the fish you need in your homeworld. Listings aren't updated daily so take them with a grain of salt.

The same goes for other types of Dark Matter, but check https://universalis.app/ for prices on your Data Center.
