I use two for different purposes.
Terminology. Straightforward Terminal. Handy right-click menu, H/V splits.
Terminator: Very customisable, for example multiple layouts (ie splits, and even custom command per split per layout), and also multiple profiles which are your choice of background/transparency, colours, fonts, scrolling etc.
Id say most Linux hobbyists are "somewhat professional" at least, to get competent in Linux you need to Git Gud. But if you are interested:
There is this (a kind of overarching, slightly long overview) and the people they talked to are professionals.

And this, a more details specifics side-by-side (for example sandboxing for each type of package):
Note as an example: All three can sandbox, only flatpak it is mandatory, but snaps and flatpak its on by default. appimage is not, it needs to be enabled. Some smaller points such as this may be glossed over (that I noticed).
For "commercial but free" There is AxxonOne (was AxxonNext) But free only allows 4 cameras. However this is better than all the FOSS choices in terms of what it can do (and so it should, more than 4 cameras or face detection, fire etc costs money).
For FOSS there is:
Lots of options but you will need some baremetal or a decently powered server and hypervisor to run in a VM.
You need to enable non-free in sources, and install rar/unrar which are not the free version. (apt install unrar-nonfree)
Is 25 minutes a long enough in-store demo test time to have a $3500 wank?
If you do go down the route of building your own (you should, that is homelabbing 101 !!!), any old NUC off eBay with 2 network ports will do (8GB ram +).
Also, since you are homelabbing, you should be looking at OPNSense not PFsense, or OpenWRT (but you'll probably quickly realise that you need OPNSense.) OpenWRT is more a drop in firmware for an existing router, think like you have an old Netgear R7000 and want to run open source and potentially add features.
How many Macos versions are there? Are they up to Macos 2K?-
Did you read someone else's post, and decide to get on this bullshit "gatekeeping" bandwagon? You're a misinformed malcontent. spew you copypasta bullshit elsewhere.
okay Judge Dredd. Because you make the difference to the Linux world. piss off back to whatever OS you were using before you "discovered Linux" 6 months ago.
sudo apt install lynx
Linux users that use the software store are not Linux users. The store is only there for your mum and dad.
What RAM does this "beelink" have (I've never heard of them)?
IPS can be very memory intensive if you add lots of rules, regardless of how their behaviour is set. (You can check the table size)
Also, what else do you have enabled? Do you have ZenArmour also installed and running? That is another memory hungry app (it does the same thing, so either use ZenArmour or IPS, not both).
Finally, do you have offloading disabled for the Interfaces? Interfaces ->Settings you need to disable Hardware CRC, TSO and LRO at the least for IPS to work. You might have to disable VLAN HW filtering as well.
These last settings are probably the most common reason for IPS failing. Drivers are almost always broken for these functions, particularly in HardenedBSD/FreeBSD. IIRC these are off by default in pf, but on in OPN.
