It's hard to make informed judgements when your life is being put into an application form and a bundle of supporting documentary evidence. There's a strong tendency is to include everything 'just in case.'

It's not the document itself that's important, rather it's what the document says.

In principle your application is personal to you.
The supporting evidential documents that are important to you may not be at all relevant or appropriate for others.

The best starting point is to review the UKVI webpage indicating Documents you need to provide

You’ll need to provide:-
- Applicants current passport (incl any previous passports)
- 2 passport sized-colour photographs (See UKVI Passport photo requirements)
- copy of sponsor's passport bio page
- proof of Knowledge of English (unless you're exempt)
- Tuberculosis (TB) pre-screening certificate
- proof of your relationship to the person you’re joining
- proof you can meet the financial requirement or maintenance requirement
- proof of adequate accommodation
- documents to prove that you meet the eligibility requirements - read the guide to supporting documents for examples.

I'd suggest reviewing the guidance on the Financial Requirement when you apply.

Also take time to review Guide to supporting documents: settlement

Looks like you've got it covered....but it really does depend on what the documentary evidence says.

Sincere best of luck with the application
