A website I use a lot is emojidb.org (f.e. https://emojidb.org/reindeer-emojis) ⋆❅*𖢔𐂂꙳

It's a great searching tool for regular emojis, but also other pictogram-looking Unicode.

It's updated/maintained by users so it understands quite a few anarchaic search terms f.e. 'fediverse' and will return suitable emojis!
