Which idea would you pursue if you wanted a steady, profitable business with the least resistance to success? I will not promote

I'm deciding between 3 online marketplace ideas and would appreciate honest feedback on which is most viable and worth pursuing. 1. Event Photography & Videography Marketplace A platform where companies book vetted photographers and videographers for corporate events, conferences and brand activations through predefined packages. The platform earns a commission on each booking. The market is competitive, with low barriers to entry and limited differentiation. 2. Sponsorship & Audience Access Marketplace A platform where brands discover and book sponsorship opportunities across newsletters, digital publications, webinars, coworking spaces, communities, clubs and events. Providers list and fulfil their own opportunities, while the platform takes a 10% commission. Similar platforms exist elsewhere, but I haven't found a consolidated equivalent in my local market. Demand and market maturity remain uncertain. 3. Clubs & Communities Marketplace A platform where clubs, social groups and community organizers book activities, experiences and venues for their members, from sports sessions and creative workshops to cafés and unique gathering spaces. It also connects communities with brands for sponsorships, product sampling and brand-funded experiences. Revenue comes from booking commissions and sponsorship transactions. Challenges include fragmented supply, small transaction values, competition and the effort required to secure sponsorships. Revenue with 10% booking commission and also from facilitating brand sponsorships. If you were starting from scratch, which would you pursue, and why? Consider profitability, ease of customer acquisition, barriers to entry, revenue potential, repeat demand and the path to building a sustainable business with minimal upfront capital.
