Dell Inspiron 5000: https://www.dell.com/en-us/shop/laptops/new-15-amd/spd/inspi...
Lenovo T495: https://www.lenovo.com/us/en/laptops/thinkpad/thinkpad-t-ser...
The main advantage of the Lenovo is that it can be equipped with 32GB RAM (and has a Trackpoint), but adding more storage and a higher DPI display brings the price up to over $2k, while the Dell is priced at $774.39...
Inspiron is also Dell's more prosumer oriented brand, while the Lenovo T series is supposed to be enterprise grade, so not sure how the Dell would stack up in terms of longevity.
EDIT 2:
Apparently the Lenovo E495 can be configured with 64GB of RAM at around $1,500, so this might be a good option for me, as well as the OP as this is a 14" model. I don't see a 64GB option on Lenovo's site, but there is one listed at Newegg: https://www.newegg.com/p/1TS-000E-0EMS3
Newegg also has an HP Envy laptop with 64GB RAM for a similar price, but I'm not familiar with that brand.
