Choose any one platform for advertising products.

Threads is great! Twitter without all the fluff and ads haha

Instagram and YouTube. If you are in the B2B niche, LinkedIn by a large margin.

I would go for Instagram and Linkedin. Instagram is a great platform for businesses that want to connect with consumers on a visual level. Instagram is also a great platform for building relationships with customers and followers. LinkedIn is a great platform for businesses that want to connect with other businesses and professionals. The platform's user base is made up of professionals from all over the world, which means that businesses can connect with people who are relevant to their industry.

Facebook Ads can be pretty effective. Laser-targeted audience segmentation is a big win.

LinkedIn is the great platform to connect with business professionals and advertise your business/work oriented projects, and for other marketplace project you can use fb, insta, twitter as well

Instagram for B2C discovery. LinkedIn for B2B. Youtube for search.
