Well, I am essentially trying to convert cassettes to CD's.

Presumably your own. Otherwise why bother...

So I think
I need the following:

- Record from source
- Small edits like
* removal of some portion of song
* removal of some portion of song but
not disturb the cycle of the rythm

Quality of the above totally up to your skills. any app...

- Good hiss removal (Audacity & Goldwave hiss removal
makes the music worse, not better, for me.)

All hiss removal is detrimental to the music to a degree. Some may be worse
than others.

- Normalize volume of many .wav files to one level

Not a big ask of any software.
