A IPS panel may be the best match for your setup (but with a higher price tag), or you go with a good (read: with a high viewing angle) TN panel.
(NB: Both techniques are of the TFT-LCD family. An LCD can be backlit by LED or by flourescent lamps. The latter are the bulkier and heavier flat-screens.)

Despite the fact that they want to sell their monitors, this article gives a not too technical overview about the panel types: https://www.viewsonic.com/library/photography/what-is-an-ips-monitor-panel/

Regarding the slower reaction time of the IPS in contrast to TN: I guess this can be neglected for retro games, which were developed when TVs with 50/60Hz were to be found in a household.

Maybe you can lend a TFT with IPS panel or know someone with an Apple device (Retina display) to evaluate the IPS capabilities, or can view the different panels in a consumer electronics store before making a buying decision.

One more thing: Depending how "noisy" your place is in terms of other bluetooth / wireless signals it may be advisable to use a dedicated USB-Bluetooth and/or USB-Wireless dongle, but this can be changed even once your arcade is built.
