My advice is segregatting work and personal environment, your company’s computer isn’t safe for general usage.
About stuff you use for yourself, don’t focus on which program you want to use, but on the task you must accomplish, most software that is made to mimic a Windows workflow are not great, sometimes you think you need a msword alternative, but you just need to create a document, there’s many ways to manipulate documents on linux that are so much better than text processors like word or libre/wps/only, and you will miss it by straight up looking for alternatives.
On Window’s software are usually bound by a lot a comercial bullshit, they have to bloat to be able to be forever at development and pushing new versions, Linux usually follows into Unix philosophy, aiming for small high quality software that are easy to compose into a bigger workflow, even when not using cli tools that operate on text streams, a gui linux application usually work with standard formats, don’t try to overlap features and are easy to replace if needed.
And about transition, i like the dual boot approach, have a linux partition, and use it for what you can do better on linux when you want to, as you get better with linux, you will be wanting to use window’s less and less.
