For more opening suggestions check out the chess openings tier lists videos by GM Hikaru Nakamura and IM Levy Rozman (aka 'GothamChess').

Note that (particularly for the beginner openings video) they will frequently refer to some openings as "garbage" or "bad" (an unfortunate choice of terms in my view). However, these qualifiers are meant simply to convey how appropriate the specific opening is for the level of player being discussed, in terms of, for example, how much so-called "theory" (i.e., the collection of extensively documented variations) the opening encompasses, or how much emphasis the opening places on positional versus tactical skills in order to play it well.
So, an opening they refer to as "garbage" for a beginner may in fact be appropriate for higher rated players who typically know more of the theory for particular openings and have a more highly developed understanding of positional concepts. For each of the openings discussed be sure, also, to note whether the evaluation is from White’s or Black’s perspective.
