Green boy maybe (he follows his crush into a gym where she was learning boxing but after getting bullied and stuff he decided to really learn more about boxing)

Mairimashita iruma-kun (this is more on the fantasy side but I really love this)

Foods are the best gifts

Skincare is usually a safe bet

yeahh^ or give em merchs of things they like

Scented candles, candy

Or maybe posters of the anime your friends likes

I mean I don't know what they're into but probably a snack or drink they like and if they have a hobby that you know of, maybe an object related to it? For example giving someone who bakes a new baking set. That or if you've taken pictures with them if you have enough make a (I don't remember what it's called) small book with the photos on each page. Hope this helps if it doesn't then I'm sorry.

Dairies (notebooks lol) ,chocolates or pack everything you want in a box and give it to her

If she has a hobby or something she /he is interested in, go for something that can be useful according to that
You can also try something more emotional like if you are really close you can print your favourite moments together and make a mini album with a heart warming message
Hmm clothes would be another option or perfume maybe or something to decorate her /his room

I just thought about gifts myself, and I personally want to buy my friends a heating compress for when they have period cramps.
I also recently gave a candle set (hampers) which is nice since u can buy it just like that from online stores. Hampers can range so it's not only candles. U also can put in your own things u bought, (food, scrunchies or even that heating pad thing) to feel more personal.
