Do I need 2K or 4K resolution for an indoor camera?

For most indoor monitoring, 1080p is adequate, but reviewers note 2K and 4K models (Ring Indoor Cam Plus, eufy E30/S350) offer noticeably better digital zoom and detail. The trade-off is higher cost and, in some cases, larger app storage footprints and the need for fast WiFi, points raised repeatedly in expert and community reviews.
