Aboleth Spawn's ability cares only about triggered abilities of the creature that's entering, not abilities of other permanents that trigger when that creature enters the battlefield.

Triggered abilities use the words "when," "whenever," or "at." They're often written as "[Trigger condition],[effect]."

If the ability is modal (that is, it has a bulleted list of choices), the copy will have the same mode(s). You can't choose new ones.

Effects that modify how a creature enters the battlefield are not triggered abilities and are not affected by Aboleth Spawn's ability. These include (but aren't limited to) entering the battlefield as a copy of another permanent, entering the battlefield with counters, and entering the battlefield tapped.
