My general questions are: which one is a good starter. Are they usable even though the price is very low? Also, I know the optimal antenna length for ~7MHz is around 20 meters so, is there any possibility of doing CW/morse at higher frequencies so as to reduce the antenna requirements?

Fractal antenna

For high bandwith, yes. Also small size.

overall gain? Not so much.

Might wanna look into sub-quarter wavelength circumference mag-loop for reasonable gain/size/directivity if you have a specific frequency you want ears on.

Mind the capacitance voltage values if you're gonna tx at anything with integer values of watts though.

I think most SDR people don't care about a specific frequency

Then fractal for ears basically everywhere

There's also trapped antennas.
