From what I understand:
Current InDesign versions will support Type 1.
InDesign versions released after mid 2023 will not support Type 1.
Therefore, at the time of your upgrade, if the latest InDesign supports Type 1, you should be OK.
Anyhow, you should be able to request XMPie Support to upgrade your Adobe InDesign server to a specific version if needed. (For example to upgrade only to AIS CC2022 so you continue to have type 1 support.) - Of course this means you will need to keep all your desktops at that same InDesign CC2022 version too.
The alternative is to go with the latest and modify all your existing type 1 fonts to TTF/OTF.
