I will mostly need it for document transfer to Word for editing and some picture and graphic manipulation.
For coverting the documents i would suggest you to go for Adobe Acrobat DC and for graphic manipulation and vector graphics you can opt for Adobe Illustrator and Animate.
For pictures and editing i would suggest Adobe Photoshop.
And the best would to get the complete Creative Cloud subscription that woul include all these applications in one.
You may also refer to the link below to check different plans and applications and their features:
Adobe Creative Cloud desktop apps | Adobe Creative Cloud and for prices of the plans you can change the region at the bottom left corener of the page.
Let me know if you need more help.
