Simplisafe warns me that it is opened but it will trigger the alarm once the sensor is closed and armed with the system if it is closed when the countdown finishes.

There's enough customization to do things like allow you to arm both systems at the same time and delay arming if a sensor is open.

Having a central hub like SmartThings, Hubitat, or Home Assistant helps tremendously, since you can run multiple protocols and tie them all together.
Otherwise, you can get WiFi enabled contact sensors. Though keep in mind that most are web based, so they might have delays.

There are ways to get some level of cohesion between them, but you do gain some redundancy by using multiple cloud services instead.
The WiFi sensors are pretty cheap, but I can't speak for their reliability: https://www.amazon.com/dp/B0BKT1RBW4
