PS4 two discs? All the content on disc?

Google tells me the Blu-ray capacity for PS4 games is 50GB. I suspect that won't be enough. The PC system requirements say 120GB storage is required, but that is after unpacking the files and it also takes a bit of empty disk space into account.

It's long been the case that a PC game cannot fit on a DVD many times over, so a download becomes the only practical solution.

Blu-Ray discs have higher capacity, but I suspect we are now also at a tipping point (and MELE is three remastered games).

The PC version requires 120 GB of storage. The only way to accomplish this on the console physical versions is to use three dual-layer Blu-rays (which is impractical), a Blu-ray XL (I don't know if the Xbox and PlayStation support those, or use a 4K Blu-ray disc (which I don't think the normal Xbox One supports). Obviously the Xbox One/Series X/Series S and the PlayStation 4/5 versions of Mass Effect: Legendary Edition have physical copies , so they will figure that out somehow. We are at a turning point with games that the size of games are becoming too large for the optical discs that are out now. In the future, either EVERYTHING will be digital (which is not practical for every country because some countries have crap internet so they rely on the physical media, but that is improving)…or similar Movie Theater formats, the manufactures will send people a read-only USB flash drive will all the game files on them but they cannot be copied or modified. Physical media will someday make a comeback, everything like that is cyclical, just look at Vinyl Records, they are coming back with a vengeance (not quite mainstream, but more people than simply "niche").
