you can do classic crossfit rep scheme of 21-15-9 and mix up barbell movement with a body weight movement, example most notorious CF workout being FRAN which is thrusters and pullups, but many other ways of mixing it up, thrusters/overhead squats/cleans/snatch mixed with pullups/bupees/box jumps,
other formats include minute on, minute off, pick a few movements and do a few rounds example max reps on each movement, any barbell movement you want light
example
min 1 row
min 2 rest
min 3 40kg cleans
min 4 rest
min 5 double unders/skip
then theres the death by format, for example death by burpees, start at 4 burpees and every minute add a rep and go as long as you can, also tabarta format, or you can make up a long chipper workout you could pyramid, 1km run/30 cleans/50 double unders/30 cleans'/1km run
endless things you can do at home with basic gear just get creative or google the crossfit benchmark workouts
