Small BGP router

Hi all!

I'm starting to work with Cisco devices after several years on Dell and open source network solutions (Force 10, Vyos).
I just acquired an ASN and some IPs from the RIPE. I need to announce my AS on the internet. I'm looking for a small Cisco router to do just BGP. Security and SD-WAN is done by a cluster of Meraki MX. Internet bandwidth is currently at 50Mbps and will never be more than 1Gbps.

What device should I use? I believe I can just buy a ISR 902. Is there some special licence to be able to run BGP? If not ISR902, which device would you recommend?

Edit: I should add that I have to use a physical Cisco router.

Thank you for you help
