Generall guide to increase strength
Number of exercises
Since intensity on this session is fairly high, close to max, you should keep number of exercises to a few.

Main exercise
2
Assisting exercises
Proposal
Few sets, few repetitions. Think extra about technique and intensity here so you end up in a few repetions with a good execution. Then the strength increase will come.
Important to rest enough to keep it sustainable.
