The latest TVs, such as the 65OLED806 from Philips, consume less than 0.5 watts in standby, which means that they are certainly not power-hungry in the household. WLAN routers that run 24/7 are certainly better suited for optimisation. A good article on this - even if it is no longer up to date - can be found at hifi.de, which has dealt with the topic in detail: https://hifi.de/ratgeber/oled-burn-in-einbrennen-gefahr-39070 The conclusion is: OLED TVs should not be disconnected from the power supply all the time if they are used frequently, except during holidays.

No, because Ambilight is built in, not every bracket will fit. I recommend ordering the TV and looking at a suitable one in the shop, or ordering one at random in the hope that it will fit the holes in the crossbars. Look at the product pictures on the Digitec page of the profile. https://www.digitec.ch/de/s1/product/philips-55oled806-ambilight-4k-oled-2021-55-tv-16276951#fullscreen=show There is a bar at the bottom of the stand that can unfortunately get in the way of wall brackets with crossbars... Brackets with crossbars are therefore not suitable depending on the holes and length.

Four-sided Ambilight is only useful when wall-mounted. The 708 will give you just as much fun.

No, the model does not have a TWIN tuner, but you could install Zattoo, Wilmaa or Teleboy TV (and others) on the TV so that you can watch time-shifted TV, record programmes and also watch others. Then the built-in tuner would be free again for other things. By the way, the TV has Android TV, so you can install a lot of TV provider apps and record and watch something else at the same time.

You can connect the Soundbar to the TV via HDMI ARC. This way you can use the system regardless of the source.

All HDMI connections on the TV support ARC or eARC. The problem will probably be that the TV does not have a dedicated HDMI OUT connection. And only one HDMI connection can output the ARC signal at a time. The TV also has an optical audio OUT (which is deactivated when streaming Dolby Digital Plus). I don't understand why, but it says so in the manual. Presumably the same applies to ARC. See p. 48 if you want to read about it).

Unfortunately, no, we don't have it in our assortment. ):

In general, only good Ultra High Speed certified HDMI cables should be purchased, because they allow more data to be transmitted. Value cables may be able to do this, but that is not certain. And it should be capable of at least 120 Hz 4K, better 8K, even if you want to use it over a longer period of time. A certified Ultra High Speed cable is a little more expensive, but it can be used flexibly and a good picture is guaranteed. Club 3D Ultra High Speed HDMI 8K 120Hz (2m, HDMI)
