Multicoin open source hot wallets/ cold storage

I've been considering using Exodus wallet for storage. It seems to have pretty glowing reviews with the exception being it closed source (bad).

Are there any other really high quality hot wallets with good functionality, UI, are open source and can store many different coins (both major coins, top 20, and ideally even meme coins (although this doubtful on cold storage))?

Alternatively, are there cold storage wallets that are good/trusted and can store many coins? Trezor seems highly recommended but it only stores Bitcoin.
