Pricing wise this is available on the Scale tier currently dubbed as "Enterprise SSO" although "B2B Organizations" probably would be more correct: https://www.ory.sh/pricing/
There are no limits to how many organizations you can have.
Regarding MFA - the MFA enforcement typically is the responsibility of the IDP the company owns. So for example dean@companyA.com use Okta and they enforce 2FA for their users. anna@companyB.com use OneLogin and they do not enforce MFA.
In terms of other enforcement, I meant more wrt to an organisation that _didn't_ use another IDP but still wanted to apply PW policies (for example) on their domain.
Could you create an Ory project (sorry, don't know all your terminology) to forward on to?
Something like:
Our app -> Ory -> split by domain -> Ory for specific domain -> Policies.
