- Which feature of object tracking I can make it work with session? As I
know the Ip route one works only with IGP.
- IP SLA will check only IP reachability but not status of session, right?
Maybe it's up but session is down.
- HSRP is not useful in this case?
What if I use static routes to ISP with track and redistributed into BGP,
any benefit?

Agree with object tracking + IP SLA sending any kind of probes to the remote
ISP router, be sure the ISP router is able to reply the probe packet sent by
the local router.
Dont know if there are hosts or routers connected to the lan ports of the
two border routers, if there are routers instead of hsrp you can make it
dynamic with an IGP.
