If you have a go in and just do work mentality and don't want to lift at high percentages of your max, then a sheiko variations sounds like it wold be good. I don't have personally have experience here, but that's become my understanding of what kind of people do best with it.
If enjoy the intensity of near max to max loads, the excitement of varying your exercises, and a lot of freedom to modify your training program then Westside is a good choice. If you haven't run it before, I recommend doing Defranco's westside take since it will give you some more structure which will be like your westside program design training wheels and then transition into full blown Westside if you like it. I make this recommendation because it can be hard if you're new to the system to figure out what works for you.
Keep in mind that Smolov and the Russian Squat cycle are peaking programs.
5/3/1 can work and there's a ton of options available including ways to work in heavier working sets if need be.
There's Mike Zourdos take on DUP. That is, daily undulating periodization. Basically, you split things into hypertrophy, power, and strength with the main lifts and assistance is there just to keep yourself healthy. There's a volume block, and then a heavy block. Great if you respond well to lots of practice with the main lifts and frequency.
There's the cube method which is a form of weekly undulating periodization which you means you do each lift once a week and alternate between hypertrophy, power, and strength each week and includes a good bit of assistance work after the main lifts.
Your not a beginner, and I'm assuming you have technical proficiency in the main lifts so I really think it's just a matter of finding something that you'll stick with and putting in the work. If a few weeks or months in, you find you hate that program then sure, pick something different. Just be careful not to start program hopping looking for that magic bullet or the newest shiniest thing out there.
