You have to decide between bent or straight elbow forehand. Did I see bend and then straight for impact on a shot? Did I see some
internal shoulder rotation ISR on a shot for forward motion?
Here is Djokovic with a bent elbow. At 2:03. 2:16 and 3:56 are high forehands.
Look at all forehands for how closed the racket face is
just before impact. See Tennisspeed article on Djokovic, link in earlier post.
Watch the line between the two shoulders and the line between the two hips. Notice also when the upper arm is moved forward by the shoulder joint and identify the shoulder joint motion. The upper arm will, for a time, be aligned with the line between the two shoulders and then move forward when the shoulder joint moves it. Stop on impacts and look at the line between the 2 shoulders, the line between the two hips, the line of the upper arm. Track those lines back and forth. A video taken from above would be ideal for viewing the forward motion of these lines and the separation angle (between hips & shoulders lines).
I believe that the forehand and the one hand backhand are 2 phase strokes where the uppermost body turns forward first, carrying the shoulder mass and upper arm with it, and then the shoulder joint is added before impact. Look for those features and timing in the Djokovic video.
The uppermost body turn (with shoulder joint & upper arm always included) is rotated by 1) foot motions, 2) knee motion and 3) trunk twisting (separation = trunk twisting). Those all show in videos.
Are you using separation?
You are husky and that probably affects your flexibility and forehand technique. ? Djokovic jumps off the ground to hit top spin on high balls. Is that feasible for you?

I just saw WTA Paolini hit a top spin forehand on a very high ball. She lost on July 23, 2022 in Semi's, Palermo. Not in slow motion. You might want to search for techniques being used for forehand high balls, variety out there?
Paolini. See if you can find her hitting a high ball. 19 sec looks like one.
Here is what Paolini has to say about her improvement-
Paolini attributes her improvements to video analysis of her groundstrokes, which has led to a more effective serve and forehand on hard courts.
"I try to open a little bit less and lower the forehand [follow-through]. I was [finishing too low]. The serve, I have to improve my serve percentage and also the spin. I cannot play flat because I'm 160 centimeters. I have to be more precise, yeah, to improve the percentage. That's what we are working on." I can't understand her forehand advice, it probably means to hit flatter. ?
4. She quoted Jenson Brooksby in her press .....

A simple issue is the racket face tilt.
Word descriptions miss other things that can be seen in videos.
