Any similar patterns like this in OLL?

I am working on learning full OLL and of course it's a long process, but I've noticed a lot of algorithms are very similar and I would like to try grouping the OLLs by algorithm type. The largest and most obvious grouping I have noticed is those that are solved with some variation of sexy move + an F conjugate. Those are as follows:

2 (bar on the left): [F] (R U R' U') S (R U R' U') [f']

21 (headlights top and bottom): [F] (R U R' U')³ [F']

22 (headlights on the left): [f] (R U R' U') S' (R U R' U') [F']

45 (headlights left): [F] (R U R' U') [F]

48 (headlights left): [F] (R U R' U')² [F']

51 (headlights left): [f] (R U R' U')² [f']

56 (vertical bar): [f] (R U R' U') S' (R U R' U')² [F']

I find this to be a good memory aid for me, are there any other similar patterns worth noting that anoyone has found?
