What exactly classes are fit wih high elves? Last time I asked about eldritch knight and everybody tell me that i must pick another race. But i dont want playing races that i don't like
So high elves have +2 to dexterity and +1 to intellect, so it's only wizard and arcane trickster rogue?
There’s no “must” about it. You can play a DEX-based high elf Eldritch Knight if you want. Or pump strength to 15 and then 16 at level 4 (or boost strength with potions) and use a long sword. It may not be the most optimised build when it comes to damage or defence, but should be perfectly adequate and if that’s the race you enjoy playing you should go for it.
You could even go for a ranger: though wood elf is more obvious because of the wisdom boost and stereotypes, rangers don’t actually need high wisdom if they pick spells that don’t use it and, while you don’t need to boost intelligence to 14 just because you can, if you do then it’s useful for ability checks and thematically will give you higher Nature. If you’re going to use a bow and keep at range, you can live with lower constitution than a frontline fighter to give you more flexibility to boost wisdom too.
If you’re willing to branch out into other kinds of elves, wood elves can make decent druids and drow decent bards, sorcerers or warlocks. Or I’ve started a run with a drow DEX-based paladin.
But as long as you’re not fussed about having the best possible version of a class, then you can use a high elf for anything. You’ll probably just need to have lower dump stats than you’d otherwise get, and reconcile yourself to living with +2/+3 rather than +3/+4 bonuses to primary attributes other than DEX or INT for EA, but that’s not the end of the world.
