I have an old-ish Toshiba Satellite L755 which I got from a friend. I already gave it an overhaul by upgrading the RAM to 8GB, replacing it's HDD with a faster 1TB Seagate Barracuda with 128 MB cache, getting an external TP-Link 5G wireless receiver, and upgrading to windows 10. It is functioning significantly faster now although it is still a little sluggish in some cases so I thought maybe upgrading the CPU would be a good addition to all that (since I have already invested a few hundred dollars into those upgrades). I already did some tinkering and opened the laptop to see if the CPU is replaceable and it seems that it is. I was wondering, however, if it would be advisable to do this upgrade, and if so, how can I find a compatible CPU? I am looking for any expert opinions I can get. Thanks!

Most laptop CPUs are soldered onto the motherboard, preventing them from upgrades but it might not be the same in your case it seems.. But your laptops's cooling will NOT be enough to keep a newer laptop cool enough. I suggest you don't mess with the processor as it might damage the board itself. Again I highly recommend you don't change the processor. I second the SSD upgrade as well as stated below. You will see a significant increase in speed with an SSD.

You can upgrade the cpu on that model. You'll have to lookup the motherboard's exact model # and see if you can find a list of suppored cpu's for it. You will also want to upgrade the stock thermal paste to something better. One of the best out there right now is Grizzly Kryonaut. It's a bit pricey though... $12 - $15 for 1g of the stuff.
Thank you all for your input. @mbilal2 and @br00n0 I will need to see if I can return the HDD that I bought and get an SSD instead, thanks for that tip though!
Thank you @toshibitsu. I am trying to lookup my motherboard model number but for some reason it only shows up as "Base Board Product Name". I tried CPU-Z, Piriform Speccy, and the "wmic" command in CMD, and they all gave me the same thing. Here is a screenshot showing the output of these three programs. CPU-Z and Speccy do give the Southbridge model as HM65, when I looked that up I found the following list of processors. Is this correct? Can I chose any processor from that list? I appreciate your help, I've moved into the world of macs a long time ago and haven't dealt with PC hardware upgrades in many years.

You may luck out and find a white sticker underneath the memory sticks that has a model # on it. Otherwise, you may have to partially disassemble the laptop to find it. That CPU list though may be accurate... if your laptop doesn't like a CPU though, you'll know. You'll definitely want better thermal paste and make sure you clean out those fan(s) if you get an i7.
