Help me decide - Client, Server or SSR

I am confused by which approach to use and I think this is causing me some difficulty: Should I use Client, Server or SSR? This is an important question to resolve from the beginning but, having searched the documentation, I can see how to select the approach.

Please would you read the descriptions below. They are two simple projects. Tell me which of Client, Server and SSR I should work with. In both projects, I am NOT using front-end frameworks. They are both simple Bootstrap CSS and possible some Ajax fetch for a bit of interactivity.

Project 1 - Presentation of statistical data This application is built in nodejs / expressjs and uses Pug view engine. It uses node fs to import data which is then written into the AppWrite database. The web pages, which contain the data, are rendered on the server and pushed to the browser.

I will use some filtering of the data on the webpage, which will require an Ajax call, to fetch the data.

Project 2 - Blogging platform AppWrite User has an admin panel where they can create blog posts. There will be more than one AppWrite User - there are three different websites. The website displays web pages and the blog posts. The website has a web form. The web form data is to be stored in AppWrite.

Thanks.

Client SDK with correct permissions on Collections/Documents would suffice too.
