Hello, Please do share your experiences regarding the inner page & home page SEO. Is there any difference in doing the submissions? Why the inner pages of a site do not get picked up quickly by the search engines?

Yes, each page has its own keywords so every inner page is different for submission.

According to me difference between home page and inner pages is that each page have their own keywords and also Mata tags and description, In home page there are all links available of each and every inner page and inner page is related to specific keyword and also detail for one keyword information.

The home page is fun and exciting but it is viewed for less than seconds, while inner page contains the real content.

Home page is the landing page of your website. and inner pages are the others page of that website.

Home page is more important to Search engine, the inner page is more partial to visitors.

Recently I heard that over Home Page optimization is consider as spamming by Google and SEO of inner page is gives more visibility on search engine.  And if your product is AirBNB Clone and you are getting more market from AirBNB clone keyword so if you do more SEO of inner page of AirBNB Clone then you will get more business for particular products and services where through only Home Page SEO you can not get more market for most important products ans services.
