If you have asked me what my all-time favourite accessory for Sony cameras is, it is this $7 IR / Infrared Remote. It is a knock-off of the original Sony version, the Sony RMT-DSLR2 from the DSLR ages ( Sony version costs $30, not bad either).
Sony RMT-DSLR2 Infrared Remote Control
The remote is small, wireless, cheap, reliable, it never misses a beat. It has all the functions you need to operate the camera. You could go into the menus and change whatver setting you wanted. I have used it with my Sony A99, A99 II, Sony A6300, A6400, A7 III but now Sony for some reason decided to remove the IR / Infrared receiver from the new Sony Alpha A7 IV , so my RMT-DSLR2 is useless with the A7 IV!
Sony RMT-P1BT Bluetooth Wireless Remote
There are only 2 wireless options to remote control your A7 IV that I know of, either to buy the overpriced underdelivering Sony RMT-P1BT Wireless Remote Commander or use your Smartphone app, none can replace the functions and practicality of the RMT-DSLR2 (Check the star rating of the app!)
Sony Imaging Edge App
I hope someone will come up with a better Bluetooth remote for the A7 IV soon.
