NAS advices?

Hi,
I'm planning to buy my first NAS for a home usage. The main purpose is keeping safe all personal files, photos, videos, documents and also save / download music and movies.
I was waiting to see if an updated version of Synology DS218 (value series) / DS218play is going to be released, but in the end I'm starting to look at DS220+.
The main reasons are:
1. it's newer (and I don' want to wait a new version of DS218play)
2. it's more powerful and since I'd like to keep it for some years but also I could require some transcoding, it could be nice to have something good and with an upgradeable RAM.
3. I'm not sure, but I don't exclude that I could start to use/play with virtual machines in the future....but this is just an idea.

I was thinking about 2 x IronWolf 6TB (ST6000VN001). Is it a good idea? I wanted to buy the WD60EFRX (which should be CMR according to WD) but they don't appear in the Synology compatibility list.

I wanted to ask you what you think about these choices.

I also need another suggestion: my NAS place is in the same room of the routing, but unfortunately not in a place where I can ever hope to have an ethernet cable.
I studied a lot about powerline adapters and wifi access points (in client mode), but I'm not able to decide. I was thinking about this TP-Link TL-PA7017 (for powerline) or about TP-Link RE450 (for the access point). Which is the best option?

Thank you!

Yes, DS220+ would be a much better choice. Not only it can be upgraded, but it also has no limits on what apps you can install or run. Value series NAS like DS218 / play do not even allow Virtual machines or anything complicated like that. Value models are for simple backup and file streaming purposes only. Not a very future proof choice. They will likely release a new 218/play replacement this year, but they will only change a newer CPU which is still going to be limited. Transcoding would be better performing on plus series with Celeron inside.WD Red or Ironwolf are both good options including SMR drives. RAID5 is when CMR would be recommended.The best Ethernet option would be via LAN powerline adapters RE450. But sockets are not on the same loop/cable then WiFi+LAN will be the option.I hope this helps.
