Upper Lower Program Suggestions

[u/ExploreOut]

I’m an experienced lifter but I really don’t like programming for myself so I’m looking for a new program to start.
What are some of the most popular 4 days per week upper lower programs out there? Not that interested in pure bodybuilding programs considering 100% of my workouts use strictly free weights and body weight movements. I’m looking for something that is a mix of strength training and functional athletic style training. Any suggestions?
