Best choice of storage for my circumstances?

Hello everybody, I’d like to preface this by asking you to excuse my ignorance and essentially asking an “ELI5” question, however..

I was looking into where to best store my current BTC holdings which are significant enough to warrant cold storage, while not being extraordinary, it’s not nothing. I have my coin on Coinbase atm unfortunately but can’t really spring for the expense of a good cold wallet right now unless I dip into my BTC to do so, which may be a wise move. If so, what’s recommended? I know ledger is not a viable option any longer.

And in either case, is there a solid option for “warm storage” I guess it would be? An exchange-esque iOS option? I’ve looked into it some and heard about Muun, but all the posts are a bit dated. Just looking for some current advice.

Appreciate anyone that is able to spare a moment to help. Thank you!
