I found this on a Reddit thread, these are likely the most correlated stocks to bitcoin:

I think other things are a bit too niche to be tracked but you should be able to load up Tradingview and have a fiddle about with overlaying charts (I think you can overlay 2 with a free account).
I'd suggest looking at emerging tech indices, AI indices as well as your suggestions..
It might go without saying but as the S&P500 has shown fairly strong correlation with Bitcoin (during bull times particularly) and as the big tech companies are the main driver of the S&P500 and make up a decent proportion of it, they'll be the ones that get a high correlation too.
Coinbase might also be well correlated with Bitcoin. I'm not sure they're as close though.
It might be worth mentioning silvergate bank was correlated to Bitcoin too until it went bankrupt.
