Buying recommendations for a new-ish player

Hello everyone! So I just noticed today is the last day of the eShop sales on Nintendo Switch and decided to check for sales on SoS and Rune Factory games. When it comes to SoS I'm kind of a new player, as I only played Trio of Towns (loved it and played it quite a lot) and the first SoS (a bit less). So I'm basically wondering which of the SoS currently on sale would you recommend me to play. Also, and I hope I'm not breaking any rules, would you recommend RF3? I played 4 quite a bit on Switch and I'm planning on playing more of RF5 on my PC, but I've heard 3 is quite different from 4 and 5, so no harm in asking first. Thanks in advance!

EDIT: Ended up getting both Pioneers of Olive Town (+DLC) and Friends of Mineral Town, plus Rune Factory 3. Sales were that good lol. Thanks everybody!!
