If you are renovating are you having an electrician install AC powered interconnected smoke detectors with battery backup? I think building codes typically require this.
The Hardwire translator cannot monitor AC powered smoke detectors. Instead, a single Firefighter audio detector could monitor a circuit of interconnected AC smoke detectors.
Low voltage smoke detectors, and all the other recessed sensors you are referencing could be used with either the IQ Pro or Hardwire Translator.
How many sensors are you installing? Are you planning on adding any wired keypads to replace the IQ Panel 2 location?
If you go with the IQ Pro, one change would be how you program the system, it uses an app vs on screen programming.
Here is a similar thread regarding IQ Pro vs Hardwire Translator:
