One way is to do equipment on one character and consumables on another. It makes sense to do all the smiths on one character because then you won't have to learn expensive motif styles on more than one character. Most important, don't hoard everything. Even if you learned all motifs, you don't need to keep style stones for all of them, only the ones you craft. Same goes for trait stones. Generally speaking, you need to prioritize what is worth keeping based on whether you use it.

Sell excess and use the gold to expand your inventory. There is at least 3 times the bank space today than at game release. We managed to get by with less space by using alts as storage. The best option now is subscribing and get a craft bag. It's the best thing that ever happened to crafting.

I have 4 crafters, whom I'm all still leveling up:

1. Smithing, woodworking, tailoring. These need to be on 1 character because of motifs.
2. Provisioning (and thieving).
3. Alchemy.
4. Enchanting.

The last three professions take up a lot of materials so they only have one each. On top of that I have a storage character that holds jewellery, trait stones and upgrade materials like resins. It is the best solution for me without the crafting bag.

I like rolling alts and I also craft for my family who like rolling alts, so I prefer to keep healthy stocks of materials on hand. If you don't want 4 or 5 characters (crafters or storage characters) that need lots of bag space, then you could always drop a few professions.
Enchantments can be found and bought from vendors, or you could use poisons instead. Food can be bought or found. You can always level up those crafts at a later stage.
Armor/weapon sets can be found as well, a lot of people farm those and they are used a lot in endgame. However, because research takes a lot of time that is still the professions I'd level first if I were you.

Depending on your budget, ESO plus for the crafting bag is a hige huge help.

Prior to that I struggled and had to upgrade my bank ans bag fully to craft

Yup. Crafting was a little bit of a nightmare before I got ESO plus. Now I have one master crafter who learns all recipes/motifs, leaving my other characters free to focus solely on their roles.
