I have 2 rooms - home theater room and master bedroom that need control.

bedroom has LG-Oled, Yamaha receiver and Apple TV4k and cable box. All but the cable box are wired Ethernet. Do I need anything more than an io extender in the bedroom to gain control? Reluctant to buy a second EA unit as I will likely never use the osd. If an extender will do it - which one is recommended. Thanks in advance.

I'd you aren't doing lighting in both rooms I would buy a 2nd ea1 as you need a strong mesh for the remote.

An EA1 would be the best option in case you decide later that the navigator is worth having, an IO extender will be overkill because it has way more IO than you need (unless you find a cheap used one), but a Z2IO would be the most economical because it has 2 IR ports (4 ir total).  You might be lucky to find an older Z2IR which is a bit similar to the Z2IO but doesn't have contact or relay options.
