Synology does all that.
I run two one at home one at the office, my only complaint is that it’s a bit “idiot proof”… both other times the web based GUIi is great. Also has free software that punches through NAT and dynamic IPs works great (quickconnect.to)
I use sftp, media server, primarily
I second that wholeheartedly, and I also run two 19" Synology NAS units, one at home and one at the office. All smooth sailing so far.
A colleague uses a QNAP instead, which he claims is better price/storage ratio at the expense of lesser software usability, and I'm okay paying a bit more of my own money (at home) as well as taxpayers' money (at work) on better usability, because it will likely pay off by saving time in the long run, as I currently don't have a dedicated sysadmin in my team.
The only question mark to date was when installing with non-Synology (enterprise SSD) drives I got a warning that mine were not "vendor sourced" devices, and decided not to take any risk and replace all drives with "original" Synology ones just because I can. This may be just disinformation from Synology to make their own customers nervous, and it reminds me of the "only HP toner in HP laser printers" discussion, but it would have been a distraction to investigate further, and my time is more valuable than simply replacing all drives.
