Couple of small caveats with 4G/5G connections, especially for a "business*" user. First if the internet is used to share large files often and/or is used for a lot of streaming it could be possible to fall foul of the "fair use" policy that many of these OTA connections have. It is rare, but it is possible. I personally have dealt with this twice for customers and it's a colossal pain...
Secondly there are plenty of deals out there for an internet connection without a landline but if there is a landline anyway, then I'd prefer it for the reliability of the connection even though the speed might be lower than 5G. A cable is much less likely to be affected by weather, competing signals and local cell tower congestion, although cell tower congestion is dependent on the exact location of the user, the and size of the local population. That's not to say 4G or 5G are unreliable, but Murphy's Law states that the moment you really need it to be reliable it'll turn to excrement...
*Since the pandemic, "business" user has become a very blurred line with people working from home much more. However I am a BIG believer in playing fair. I have been able to work from home like most people but a recent change to my circumstances means I am now fully based at home for my work, essentially making my home my actual place of business. So I changed my connection from domestic to business. It 'costs a little bit more but there are benefits like a much reduced SLA when reporting faults, dedicated support if things do go wrong (not so far) guaranteed speed (hence why I measure my speed often as mentioned earlier) fixed IP address (very useful for a someone like me) and no fair use policy to worry about irrespective of how much of a battering I give the connection.
