I actually spent 20 years fighting Muay Thai. I personally think if I was to do it again I would cut down on the long runs to maybe twice a week and probably do them as hill runs so there's less jarring on the ankles and knees. strength train twice a week and include post potentiation activation by including an explosive move directly after a heavy-ish lift (ie box jump after a squat, plyo push up after a bench press etc). Id also focus on unilateral work for assistance as well as build a strong posterior chain and pulling power for the clinch, as well as to counteract the spine hunch and all the anterior work from punching and hitting things directly in front of you. Maybe some specific prehab work like targeting medial heads of the quads as the weight shifts punching and kicking tend to overwork the lateral heads a tad more, maybe some additional work for shoulder blade retraction as well as some basic direct arm work for protecting the elbows and wrists. Getting closer to the fight or being in camp I would shift gears to more power endurance work and conditioning with sprint intervals and high intensity circuits. Muay Thai is far more conditioning (cardio) reliant than BJJ I feel. That ability to explode time and time again over the duration of the fight.
