Should I have heard from Plusnet that they won't be offering landline service from January 26?

From memory the Hub2 only has 3 ethernet ports with Full Fibre.

Other than buying an ATA and a ethernet switch you could consider getting a new router like the FritzBox 7530 (the AX version has better WiFi). There are others you could consider.

While the 7530 only has 3 ethernet ports available it has a built in ATA and a DECT Base Station.

When looking at using a separate ATA and Ethernet switch, don't lose sight of your other need, that is to keep a phone working during a power cut. A combined router with bulit in ATA plus the ONT minimises the load during these periods. I use a Fritz!box 7530AX, which under normal conditions uses less power than a Plusnet hub.

I have one of these:  https://www.amazon.co.uk/SKE-20000mAh-Uninterruptible-Supply-Battery/dp/B0CQR5GMN4/ref=sr_1_4?crid=2... that keeps my system running for many hours.

You will need an adapter such as one of these if you are using a Plusnet hub as the BT/EE/Plusnet use an input socket with a non standard central pin: https://toothbrushbattery.com/buy/bt-smart-hub-home-hub-dc-power-plug-adaptor/.

I have a cordless phone, so my built in ATA is fitted with a double output adapter, the ATA feeds both the cordlesss base unit and a cheap wired phone. This is kept with the ringer switched off so that it is not a nuisance under normal circumstances. During a power cut it is simply a matter of switching the ringer on.
