A beginner using a Westside Barbell type template would do best sticking with exercises very similar to the comp lifts and working up to a 3-5RM vs a 1RM. This way, the beginner would be able to build up the muscle mass they need and get more practice in.
When you use the term ME, that typically refers to Westside Barbell training developed by Louie Simmons. The point of ME according to his training philosophy is that it increases inter-muscular and intra-muscular coordination. The first is the ability of the body to synchronize the different muscle groups together and the second is the ability to recruit a larger percentage of the muscle fibers within a muscle. Essentially, you're learning how to strain against heavy weights.
In Westside Barbell, you switch out the ME exercise to avoid accommodation. In their theory, if you keep up the same ME exercise for too long, you won't be able to get better and you risk overuse injuries and psychological burnout. For the beginner, you switch every 3 weeks since it will take longer to accommodate to exercises since you're less coordinated and so you can learn the exercise.
Also, ME lifting adds the specificity maxing out which is done in competition into training. Rotating exercises is not specific, but necessary because of accommodation.
For 3 weeks, you might do box squats, then the next 3 weeks, you do manta ray squats. And you might not even go all out each week in the Westside Method. If you're feeling beat up, it's totally okay to do some sled work instead. Or you might wave your weeks. Say you're doing 3RM's. Week 1 work up to 95% of that 3RM, week 2 97-98% of it, then week 3 go all out and try to break a record.
If you're really interested in ME work according to what the term actually means, I highly recommend getting Jim Wendler's The Max Effort Method. I firmly believe that this is the best book explaining what the max effort method is all about and how to implement it.
If you want to work up to simply heavy singles, there are 5/3/1 templates by Jim Wendler that call for that.
But the best advice I think is to go check out that Darkside Barbell out. There's no replacement for training with a dedicated team.
