Anyone care to help me figure out which MacBook Pro would be best to upgrade to from the Intel i5 for music production in Logic Pro?

Upgrading from this:

Year: 2019

Size: 13"

Processor: 1.4 GHz Quad-Core Intel Core i5

Graphics: Intel Iris Plus Graphics 645 1536 MB

Memory: 8GB, 2133 MHz, LPDDR3

SSD: 250.69GB

MacOS: Sonoma 14.1.2

I use a lot of stock/third-party VST/VSTI plugins in my projects. I often get the "System Overload" and Sample Rate errors, Crashes, and it doesn't take too long into working on a project for the computer to get heated and the loud fan to kick in. Over all I feel like this computer has significantly slown down, so, I'm thinking it's time to upgrade. I'd also like to eventually get into more advanced music productions and I'm definitely going to need something that will be ready to handle that kind of workload in the future, so I'm keeping that in mind.

I'm heavily leaning toward the [ 14-Inch, 11-Core CPU, 14-core GPU, 36GB UM, 512GB SSD ] configuration.

Correct me if I'm wrong, but, paying an extra $200 more for just one more core doesn't sound like it's worth it, right? Like, I'm already gonna be jumping from 4 cores to 11, that's already huge for me.

I would like a TB of SSD, but I'm not sure I can really justify paying an extra $200 for a TB. I mean it's already gonna be an expensive purchase. Plus, all of my logic projects get saved to icloud drive, so they're not really taking up any space.

I have a little over 3K samples from SPLICE on my computer which takes up close to 6GB of space, but I just delete them when I finish a project and then re-sync when I start working on a new one.

Music creation takes up 78.58GB in total, and that's just Logic's Stock stuff alone. The Stock Instrument Library takes up 70.17GB, and the Apple Loops take up 7.89GB. Right now I'm sitting at 84.76 available space after all the other apps are taken into consideration, so 500GB SSD would be a nice enough upgrade.

And lastly, I heard that Apple's latest M3 Pro chip in the new 14 and 16-inch Macbook Pros have 25% less memory bandwidth than the previous M1 Pro and M2 Pro chips? Obviously that's not going to affect me since I've never experienced the M1 or the M2 chips in the first place, but I'm wondering if any of you have upgraded to the M3 and felt it was worth the upgrade, especially when it comes to music production? I know memory is really important.
