Try to measure up your space, use example measurements in width and height from a 50" model and see if it fits. Do not use diagonal, you'll be surprised how small, larger TVs are.
43" is very, very small for an UHD and manufacturers haven't been making good TVs below 50" for some time now. It's just not worth buying a smaller, cheaper model in my opinion.
If you can fit a 48" LGs A1 OLED will be a great option for you, or one of the starter HDR models in my guide here. If not, if you can wait we should see 42" OLEDs this year.

eARC isn't important unless you plan to connect a soundbar or AVR to the TV and use the TV to route HD audio from a console or UHD Blu-Ray player back to your connected sound device.
For streaming, both externally and internally eARC is not used, even for Dolby Atmos.

OLED vs IPS LCD vs VA LCD Panels One of the most important decisions, if not the most important when buying a TV is the panel type a TV uses. When deciding which TV to go for, you must first choose the type of panel you want from a TV. VA LCD Panels Pros Higher contrast ratio. Deeper blacks...
