probably not unless they release in some collection later on im not opposed to it if the opportunity present's it's self (im considering some of the cold steel games because they are also on switch) but tracking down 3-7? games individually nah. and that is not including the games before that.
that being said I was fully aware of it being the epilogue and i bought it anyway which tells you how much i value starting at the start.
Trails is definitely a messy series to try and get into if not playing on PC. The Sky trilogy and the first two Cold Steel games were published by Xseed, then Falcom switched to NIS America for publishing, which is why there's no releases for the xSeed games on modern consoles. They completely skipped localizing Zero and Azure (the Crossbell duology) until recently, after Cold Steel IV was already released in the West, so people who played CS without those missed a lot of the context that happened in the Crossbell games, especially since CS1 and CS2 took place simultaneously.
Basically, someone getting into the series now without playing on PC will have gaps in the series. And as a series that is all connected through characters, stories, locations, events, etc, there's plenty of missing context because of it. The PS4 does have access to CS1 and CS2, but aside from Revierie, the Switch only has Zero, Azure, CS3, and CS4 (4, 5, 8, 9).
However, since you don't seem to mind not playing through everything, I would still recommend the other Switch titles. Even though the games are all connected, the four available on the Switch can still be enjoyed on their own. I would just recommend playing them in pairs (Zero followed by Azure, and CS3 followed by CS4) since those pairs are essentially each one game split into two parts.
