Does it make sense to buy the newest Apple MacBook Pro 16" - 2.4GHz 8‑core Intel Core i9, Turbo Boost up to 5.0GHz, with 16MB shared L3 cache when I currently have a MacBook Pro 2018 (Sep 2018) 2.9 GHz Intel Core i9? Will I see enough of a change for an additional 2,500$ after trade in? Pros and cons appreciated.

if your current computer is not doing what you need it to do get a new one. If it is doing the job you need, don't buy a new one. Only you can decide.
a Computer is NOT an investment. It is a tool that allows you to do useful work.
I agree with BobTheFisherman: If your current computer is falling short of your requirement is some fashion, you should replace it, with a computer that can better meet your needs. BUT: be sure to punch it up in the areas that are falling short.
Old versus new
