I have the same issue with short nose saddles - inner thigh rubbing.
I feel like these short nose saddles aren't really suitable for audax and similar ultra-distance type cycling. They're designed for single position sitting - which is something you don't want to do on these kind of rides. You generally want to have multiple positions to cycle through, the same logic with multiple handle bar positions for your hands.
Their promo material on their website (underlined for emphasis), and I also remember Specialized Power Saddle having a similar kind of focus from users and reviewers when it was introduced years ago:
Where a traditional saddle shape encourages riders to shift their position frequently for better leverage, Argo puts the rider in a more planted position, making for greater stability and better weight distribution.
