[MCU] In order to obtain the soul stone, "you must lose that which you love". What's the minimum amount of love required?

As an example, I would be relatively upset if Richard Dean Anderson (MacGyver/Jack O'Neill) were to be tossed into the void, or my boss, or any number of people I interact with daily. Normal people continue to live their lives even when the most precious person in the world is taken from them, so where's the cutoff?

I suppose it must be subjective.  Gamora feels no love from Thanos, but killing her nevertheless fulfills the criteria.  The love seems to be something felt by the sacrificer.  And as far as we know, it's just binary: you either love someone or you don't.  So, as long as the person obtaining the stone loves the person who is lost, the price is paid.
