'Sacrifices' is puthujjana dharma, as follows:
And what is right view that is accompanied by defilements, has the attributes of good deeds, and ripens in attachment? βThere is meaning in giving, sacrifice, and offerings...' MN 117
'Householders, if wife and husband want to see each other in both this life and the next, they should be equals in faith, ethical conduct, sacrifice (caga) and wisdom...' AN 4.55
'Sacrifice' is, for example, what a husband does so he can win the sexual favour of his wife.
If we think we are 'sacrificing' something, this means we still value the object of sacrifice.
Where as the Path is from dispassion. When there is dispassion & disenchantment towards all of the world (as the Buddha taught), there is nothing of value to sacrifice.
For example, Abraham was prepared to sacrifice his son Issac to please his worldly God. Where as the Buddha left his son to attain Nibbana (freedom from the world).

"ethical duty to acquire knowledge in order to improve our understanding" means, if we stay stupid, we will create bad karma (trouble) for everyone , therefore we must learn, in order to understand what to do.
"Must learn" - there is no debt here.
"Must learn" - there is no common right.
If we don't learn, we will keep getting everyone in trouble. That's what this means.

In some cases it seems like a Bringschuld -- e.g. the "debt" (of gratitude) which you owe to your parents is apparently to be repaid "to" your parents (so, by analogy, "at the creditor's domicile").
I think that when the Buddha taught, it was out of compassion -- and the way to "repay" that was by practising properly and benefiting -- so for example the Buddha requested or advised (in MN 103) that the monks should not quarrel amongst themselves. Perhaps you'd call that a Holschuld, i.e. an action performed by the monks in their own place and time.
Finally, assuming that Rahula gained understanding as a result of "reflecting" on his actions as described in MN 61 -- I'm not sure I see any "debt", at all, associated with that.
