Too many APs is also bad. If you happen to get decent signal from the other room, your device might hang on to that connection longer than it should, giving you a relatively poor connection. It really depends on how much the signal is blocked by the walls. My parents' house has some thick/double-brick interior walls, so I am aware of how much that can kill a Wi-Fi signal. It would be best if you could install one AP first and see how it does, then add another if needed. How close are the offices? I was picturing them right next to each other, but it looks like you didn't actually say that. Depending on the layout, you might be able to use "invisible fiber" to link them and get Ethernet in Office 2 as well. https://www.amazon.com/InvisiLight-Home-Fiber-Kit-Installation/dp/B0F8DQW36V/ is the all-in-one premade kit, but you can buy the components to DIY the same sort of system. Run Ethernet into one media converter, transparent fiber comes out and is routed to the other room, fiber goes into the second media converter, and Ethernet comes out. https://www.amazon.com/dp/B0F9HQS9SN/ is the cable with LC connectors installed. https://www.amazon.com/dp/B09Q81KLRP/ is a pair of 1Gb media converters with LC SFP modules. If you need a switch in each room anyway, you could get a couple https://www.amazon.com/dp/B0G19C3F48/ and plug https://www.amazon.com/dp/B0DPG4RK8F/ into them (instead of using the pair of media converters). https://www.amazon.com/dp/B01LWA648H/ is the 10Gb SFP+ version, if you wanted to spend more and get a faster link between the switches. This invisible fiber might even work for wiring up other areas of the house too, and save you some cable-running effort.
