Hey, yeah I’ve actually built something very similar last fall. I converted an old storage bench into a motorized TV lift for our guest room. The wiring part isn’t that bad if you follow the product manual carefully and know how to hide cables neatly. I used a heavy-duty actuator from Progressive Automations that’s strong enough to lift a pretty big screen – this one to be exact 2000 lb linear actuator: https://www.progressiveautomations.ca/products/heavy-duty-linear-actuator. It took some trial and error to get the mounting bracket aligned perfectly, but the result was worth it. One tip: make sure you leave enough clearance behind and under the screen for airflow and cabling. I also added a simple remote switch system to make it easier for guests to use.
