Sony XAVC-HS with Catalyst Prepare stabilization plugin workflow - proxy or optimized media?

I bought a new Macbook M2 Max and try to edit Sony XAVC-HS Footage in UHD 10bit 422 from my Sony FX3 (Same codec as A7SIII) with the Sony Catalyst Prepare Plugin. So I am able to stabilize my clips in post if necessary. Now the codec not an easy one to process and the Sony Plugin seems to slow down everything even more, although stabilization is not even activated yet. I think I will not be able to edit a timeline for a 30 minute Documentary with original media. So I tried to switch to proxies. They work fine as expected BUT I cannot see the Sony stabilization effect anymore. When I activate proxies the stabilization gets disabled in the viewer. So I can edit my documentary with proxies but in the end when I have to grade, apply effects and stabilize I will have to switch back to originals and the system will get so slow that I will not be able to finish the whole documentary. How can I prevent that? Is there a way to use "optimized media" instead of proxies with metadata? I tried to convert XAVC-HS to XAVC-I in Sony Catalyst Prepare but then all my stabilization metadata is deleted. How can I use a lightweight codec and still be able to see stabilization results in the viewer? Thanks for your help!
