App in the Air, a cell phone app which also has a web presence here, might work for you. The website lets the user specify a departure and arrival country, including EU and inter-Schengen pairs, and displays the exit and entry protocols of the governments involved. The few pairs I tried also showed links to the various countries' governmental website.
I have not used it for travel, and have no affiliation.

Is there a site that I can refer to for up-to-date information about which borders within the EU (specifically the Schengen area) are subject to checks due to Covid-19?
https://reopen.europa.eu/. Europa.eu is the official website of the European Union. For each country, they provide the information on air/train/car/bike/boat/etc. entry. Seems decently up-to-date, though I've seen some inconsistencies with IATA.
