Ditto to Tomochan's comment. I think maybe a lot of folks consider Battle Rifles to be post-WW2, but I think that the Garand squeaks into the Battle Rifle category
It also would make a great addition to your M305/M14 platform, since it's the direct predecessor. I built 2 of them, following along on the garand build thread from this forum. While some folks built them pretty cheap, mine both ended up being slightly over 2k$, but they both have NOS barrels and NOS or very good quality parts. One of them was sent to Vulcan for refinishing and he did a great and high value job. The other will likely follow later this year.
It's a fantastic rifle, very well thought out and put together. Now is also a good time to get into them, because the prices will only continue to increase. They can be bought used on EE for anywhere from 1200-1800 commonly, with really shiny ones (NOS or Kreiger barrels and so on) being closer to 2k.
The exchange rate isn't helping people finishing up their builds, and parts are starting to get scarce, so buying a complete rifle may be the best option today.
As far as other rifles go... tbh I don't know that there's a ton of value in some of the alternate platforms. The 542 is pretty pricy, the SVT40 doesn't have a ton of aftermarket support. If you want something to hand down to the kids, a Springfield M1A or a Garand is the way to go.
