First 2 1x2x3 blocks - ZZ Multislotting, Block Cases(Front, Back, Right, Left), Diagonal Cases(BackLeft/FrontRight, FrontLeft/BackRight)
Reading what types of block/diagonal cases there are might be a burden because it will only slow you down, but keep in mind that there are about 41 algorithms in total!

CFOP users shouldn't switch to this method, but instead just learn the 82 multi-slotting algorithms.
There are special cases for F2S in which you do the slots in diagonal order. But this is still included in the (near) 41 cases.
EFOP doesn't require much look ahead, but just remembering where pieces are for your first 1x2x3 block. When you get 1 side
completed the next side should be very easy because there are so many places 4 pieces + cross can be.
Advantages towards normal CFOP:
*50 Less Algorithms.
*F2L is solved in 2 Looks, instead of 4.
*Can be adjusted and variated(best if you know all the f2s algorithms) to do diagonals, and 2 single f2l pairs.
*Its multislotting is more efficient than CFOP's multislotting on average
*<R,U,L> Move group
*All the last layer edges will be oriented on the insertion of the last f2s block
Disadvantages:
*Requires recognition and looking ahead of 4(cross style) to 5(zz style) pieces.
*EOline may require months to complete in 15second inspection.
*A very difficult method, but very efficient and algorithm friendly.
