Strength Programs that are easy to follow?

I've been weight lifting for a couple of years or so but still consider myself a beginner. I feel like I'm not getting a proper full body work out when I'm just randomly choosing different strength training exercises. I enjoy things like 5x5 because it's so easy to follow. Are there other programs that I should look out for? And is it okay to follow multiple at once? (Also I'm new here. Is it okay to ask questions like this in this tribe?)
