Returning to strength training: need a simple 3-day full-body home routine

[Thomas.L]

I'm getting back into strength training after a long hiatus and want to build a simple, effective full body workout routine I can do three times a week at my home gym, which has a barbell, dumbbells, and a bench. My main goals are building general strength and muscle, not specializing. I'm considering a basic structure of squats, bench press, rows, and overhead press, but I'm unsure about optimal sets, reps, and whether to add accessory exercises like curls or planks. What does a balanced, sustainable full-body split look like for an intermediate lifter?
