for both of the above i would suggest looking at kolla-ansible or openstack ansible (OSA)
my personal prefernce between the two is kolla but both are production ready deploymnets with good
upgrade support and fast release cadnace following a new upstream release.
both support debian as far as im aware too.

if you want to use debian triplo is not an option

there is aly the option of the debian openstack installer.
zingo can tell you more about that.
i have not personlly used it but i hear good things about it
i belive its based on puppet which is not really my preference im much more partial to ansible based installers
but if debian 10 is what you are targeting its proably a good option to consider.

there was an anounchment about deabin lts/10 exteding there lts supprot for rocky recently so its well maintianed long term.

kolla is still my preference but that is more as a developer and home user for its simplicity and feature set.
OSA or the Debian installer might suite you bettter depending on your usecase.

in general i would recommend using an existing installer for openstack vs creating your own or using
the puppet/ansible moduels to build your own. long term if you use an excisting installer you will benifit
form the maintaince and skill set of the comunity that maintain it.

most installers provide fully ha production ready deployments.
i would recomend mangain ceph externally via cephadm regardless of how you deploy openstack.

that is what kolla does i think its a solid option for many usecases
if you dont like docker or down want contaienrs you dont have to use them to deploy openstack
