that's a huge question because there are so many things to know about what kind of training have you do and what are your short and long term goals? What are your main lifts you want to progress?
I may not know you well enough to provide you with any insights unless you want to provide some background.
In the past of done A/B/C (B would be accessory work light stuff) but I did all lifts each session and alternated volume and intensity...so if I did high volume squat, I would do high intensity deads and than flip that on the next session....not sure if that's what you're looking for...FWIW..I don't keep a fixed training day....I go by how I feel...for the most part my upper body can handle a lot more volume so I only need in most cases 1 day of rest....lower body need 2 days rest in most cases...but there are times I will make game day decisions whether I am recovered adequately....I've learned over the years to listen to my body vs. a calendar.
Some guys do well on a fixed schedule....
I am running with a 5 week pendulum type cycle..this incorporated volume early in the cycle and swings into intensity......if your interested I can share more about it...
