As hamster said new screw on freewheels are widely available, but mostly cheap "for e bike" use ones. I mean they work, but on a hope Ti hub I´d think they would be a bit underwhelming.
Period correct ones in mtb gearing combos are harder to come by and do not come with HG cogs if you fancy such modern extravagance. Top of the wishlist would be Shimano Dura Ace 7400 or Sachs Maillard.
Normal cassettes (for cassette hubs) do not fit and they mostly come with manufacturer specific sprockets, so no cross compatibility either. Good thing then you normally can´t get them without sprockets.

Shimano 6 and 7 are fine for index.
Avoid Megarange
If you want 8 on the back, or 42/44 largest up front, go for a freehub instead.
Don't buy off amazon etc there are fakes out there, unbelievable cr4p.

Due to the hubmotor Ebikes using freewheels there are vendors supplying 7, 8,9 ,and even 10s parts. The play in the bearings makes indexing over 8s questionable to me. The manufacturers seem to be coming out of the BMX market space where freewheels are still used.
DNP is a brand. I took some single speed Chinese freewheels apart (including DnP) and wasn't impressed. A single wire spring wraps around all the pawls. The notch for the spring almost cuts the pawls in 1/2. if the spring breaks you lose all the pawls. They aren't sealed and rely on heavy grease, which does make them quieter than more expensive (single speed) offerings. They're cheap, if you find one you like I would suggest having a spare.
Whatever Chinese sources work for you, or Ebike shops should offer them. They do go down to 11t, where the classic ones stop at 13t.
The 6 pawl 72 POE versions aren't any stronger than the 3 pawl 36 POE parts. The pawls work in sets of 3. more noise, and more drag with the high POE parts. I have no idea what's inside the classic freewheels mentioned above.
If you take one apart they use loose ball bearings, and they're adjusted with shims. Perhaps better bearing and some custom fitting might improve things?
I've never used these.

The re-emergence of freewheels for e-bikes is intriguing (I tried to crack one but couldn’t 
) but I think the OP first needs to go over to Sheldon, grab a brew, and do a bit of concentrated reading.
