Fighter with pact of the chain warlock familiar gives advantage on attacks with help action. That way you generate advantage even on creatures that are too big to shove and it can scout and a few handy spells and abilities.
Other option could be beast master ranger but easier to resummon familiar imo

Considering the large number of feats a fighter gets, you would be better off with the magic initiate feat and the find familiar spell. The owl has flyby, which is probably the best option.
