Lots of parts can be intimidating. That is a fact, but it is the amount of parts that go to make up the detail that model builders are wanting in their kits now.
If the amount of parts with the tracks bothers you and these can be pretty intimidating then you can go the AM track route.
When I do an armour build my first things are to replace the tracks with metal aftermarket ones. Quite often kit producers don't get the thickness of the tracks right and as most of my armour is German then they need to hang right on the runs. Trying to get thin underweight tracks to look heavy and hang realistically is more work that I am prepared to do, so metal tracks that do the job all in one and just need putting together and painting is the easiest way for me.
Friul have a considerable range of metal tracks for Shermans. Just choose the ones that match the kit ones.
Of course, those who have more knowledge of Shermans than myself will be able to advise better.

The other thing I look at is replacing the kit barrel with a metal one from either Aber or RB models.
Unfortunatly I don't think either of them have one for this kit at this moment in time.
Don't be intimidated by the amount of plastic in the box. There is help here and when you start looking through the instructions.... and spend lots of time doing that BEFORE starting then you realise that when you break things down to the sections (lower hull, suspension, wheels, upper hull, detailing parts, turret, etc.) then things don't seem as bad.
These kits (Meng, Ryefield etc.) with time spent on them come out looking fantastic and always look good in the cabinet.
This is my Meng Panther A.
Ryefield Panther G with clear hull& turret. For some reason I never properly finished this, probably due to illness and it suffered as part of the declutter. It will be replaced and rebuilt!
So there is lots you can get up to with this kit. Just take your time.
