Help for my second tour?

I completed my first tour last year from Bolzano to Munich via Via Claudia Augusta, and I’m planning more trips. I’d appreciate input on weather, accommodations, and scenery for routes that meet these criteria

Constraints:

• I am based in italy and I prefer using trains to reach my departure/destination, though I’m open to international travel for a once-in-a-lifetime experience.
• Two trips: one planned for mid-April and another in late May.
• I need access to showers, so no wild camping.
• 5–7 days per trip, planning 50–100 km and 1,000–1,500 m climbing per day.
• Suitable for a capable, non-suspension gravel bike (climbing is fine).

Nice to haves:

• I don’t require 100% dry weather, but I’d rather not be soaked every day.
• Plenty of forests.
