I think https://spaceengine.org/ fills part of your request. I haven't played it but I've watched videos about it and it looks like you can jump anywhere around the observable universe and look at any object you want.

This looks terrific. But it's Windows-only.

I think it's available on Steam which would mean you could theoretically use it on Linux with Steam's Proton compatibility layer.

Can that be tested before purchase?

Steam has a generous return/refund policy [0], so you could buy it, test it, and if it doesn't work request a refund.

Side note: Elite Dangerous is on offer at the moment and that has been the only thing to give me that unnerving sense of scale you get when travelling between systems.
