I wouldn't waste any money on DDR4 at this point. The only excuse I could think of is if you have a motherboard that requires DDR4 and your current RAM is not working. Otherwise, get a motherboard that supports DDR5 and you're good.
A good reason for staying with DDR4 at this point in time is if you need faster boot times. DDR5 makes computers boot slower because it's less stable and needs more work during POST to get stable.
In many cases it's not a requirement though, and the speed improvements of DDR5 after boot outweigh the extra boot time.
Initial Training isn't done on every start. Training only happens when you change the configuration.
There are much more steps than just training. Even after training you still have slower boot speeds.
