ARMA 3 has this game mode called King of the Hill, where 3 teams fight to secure sector control. It's in some ways similar to Conquest. There's one version that's more focused towards an infantry experience and it doesn't feature any of the heavier vehicles like tanks or attack helicopters or jets. It does offer cars, trucks and transport helicopters though.
You don't spawn on squad members or spawn beacons. Maps in that game are also substantially larger than in Battlefield, so you need transportation to get to the front line, as walking would likely take you more than half an hour. The game mode has an economy system that rewards players for playing the objective or helping teammates. Helicopter pilots are rewarded for successfully dropping players within the area of operations. Players can buy their own vehicles, but since that costs money they are incentivized to keep the helicopter alive. There's also a single big chinook helicopter that spawns for free on a timer.
I'd love it if Battlefield had a similar game mode that uses the Battle Royale map, with an added base for each team. The game would dynamically assign sectors to capture and the teams could actually use transport helicopters to ferry players.
