[Blind-sysadmins] NAS storage experiences and recommendations?

Hello SysAdmins, Currendly I'm using a WD NAS unit; however due to security and performance reasons would like to change it as soon as possible. I have looked Synology NAS devices, they makes me excited. It seems that we can install Apache web server and many 3rd party apps to use on the LAN. Do you have any experience for Synology devices? 218+ seems well. Some users are installed Ubuntu and NextCloud to Western Digital NAS devices pro series PR2100/PR4100 and they said that performance and security problem nearly fixed with this combination. What do you recommend for me? Does the web interface and build-in software UI is accessible with screen readers on Synology? Thanks in advance.
