I wouldnt worry too much, just try them all on here and find one that feels comfortable then learn the basics of it.
Im finding OTB these days that openings are not a biggie, im playing people in the 1700-2300 range and we normally both out of book after seven or eight moves. With white I just play 1.Nf3 2.c4 3. g3 and generally know plans rather than specific moves
With black I play the sicilian and know surprisigly little, but it never seems to matter. Vary rarely even get a mainline. Play the dutch against d4 after 1...e6 first to avoid all the dangerous stuff and again know a few lines up to around move 10 and that is it
