Approx how much additional charge would an Eneloop AA cell hold after it
has been through a few charge/discharge cycles?

I'm wondering how worthwhile it would be to charge/discharge new Eneloops.

PS: How does that improvement compare to the improvement of conventional
NiMH by doing a few power cycles?

Don't have any precise results but whenever I get new eneloops, hybrio, or any
other low self discharge nimmies, I treat them as I did the earlier versions
by doing a 'conditioning' cycle first thing before usage. [Maha MH C808M]
Yet to experience any issues using my method.

A single conditioning cycle is probably a agood idea anyway because ISTR
Eneloops are sold with only a 75% charge.

Do you know how much increased capacity you get by doing a second or third
conditioning cycle from low self discharge NiMHs?

Since I often just top off the batteries before a planned photo session I only
do subsequent 'condition' cycles about every fourth charge event or after a
prolonged non-use spell and haven't tried to measure the results. I also have
the [Maha MH-C777PLUS] which does do a capacity evaluation but it's only for
the battery packs on my handy talkies. I did notice recently that after only a
little over five years one of the Lithium packs for the handie is down to
about half capacity. When the batteries seem to not be holding a sustained
charge even after a conditioning cycle, I usually just replace them.
Next 'must have' item for the process will likely be a ZTS-MBT tester.
