For 2, one of the few pieces of Windows software that I haven't been able to replace in Linux is GetRight. Many HTTP servers support downloads starting at an offset from the beginning of the file, and GetRight uses that to allow download pausing and resumption.

It was a real life saver back when I had an extremely flaky Internet connection.

Wow, getright! That's a throwback. I used that in the 90s.

On linux I use aria2c for similar tasks. It can resume http downloads, as well as split them up into multiple threads for faster downloading.

It's cli-based and powerful (therefore perhaps a bit confusing at first), but there are UIs for it as well for a more get-rightty experience.

I think jdownloader also has some application here, though it's mostly for getting things from those ad-filled file hosting sites frequently used by those on the high seas

Why would you multithread it except for heaving mutiple paths of entry to your home connection or you are getting a throttle from the file hoster?

Basically that. I don't do it much anymore, but it used to be helpful.

Firefox does that out of the box.

Have you tried JDownloader?
