A budget of $1,000 is not a huge amount these days, sadly. Still, the Canon Refurb store does offer cameras that they are selling under that banner: although they may be brand new over-stock, opened but not used, on display etc. If they have been used they have been checked, any remedial work done and come with a Canon warranty - so, good as new.

I would echo Demetrius' message about the withdrawal of Canon from the DSLR market. Now, what that means to you depends on your long-term intentions. By that, I mean that while I recognize you are a photography major, if but don't intend to take it on further and are unlikely to want other gear in the foreseeable future, you could pick up a bargain in the DSLR line. If you decide to stick with DSLRs, then I would suggest the 80D or 90D. I have owned both, and actually kept the 80D over the 90D because it has better dynamic range and low light performance IMHO. Pair that with the excellent EF-S 18-135 IS USM lens and you will have a great lens with fast, silent focus for both stills and videos.
On the other hand, if you can see yourself engaged in this as a longer-term activity, then I would strongly suggest that you have been gifted the opportunity of funding towards what is now the established standard for camera systems - the Mirrorless Interchangeable Lens Cameras (MILCs). While I would feel aggrieved at having my gear taken, your insurance is going to give you a cheap way out of an obsolescent platform. For portrait and video work the face and eye tracking are significant benefits and you will find they make a significant difference to those kinds of imagery.
Considering you are a photography major, I am going to give you an options for more longevity but similar to what you had before, I would suggest going for the EOS R10 - it is second only to the R7 in the APS-C crop sensory group (which your T5 was). I recommend that as it has a lot more flexibility to use different buttons on the back of the camera and will likely feel very similar to your T5 as far as layout goes. The T 50 has fewer buttons and controls, which can be a bit cumbersome when needing fast functionality, but shares the same excellent features as the R10 - an excellent 24MP sensor, face and eye tracking and great video. I would personally avoid the R100 - which is more for people who want something a bit better than a cell phone but it lacks the sensor, and many other features of its more sophisticate siblings.
People tend to concentrate on bodies and forget the lenses, yet I hope you are finding that, in fact, optics play at least as important a part as the camera body and often represent a longer-term investment. The EF-S 18-55 and EF 75-300 lenses you used to own were (TBH) pretty mediocre units, but the new optics are much better.
You will have a couple of possible choices: the RF-S 18-45 and RF-S 55-200 lenses can be found paired in kits, but for general work I would start off with the RF-S 18-150 which will cover all the applications you indicate in one lens.
One day, if you have more funds, you could consider the newly-announced Sigma 18-50 f/2.8 lens, along with several other high-performance optics to be released by them in the forthcoming future - they are more expensive than the Canon units, but you definitely get what you pay for.
cheers, TREVOR
