Finland visa from the UK, but want to go to France primarily

Just managed to book an appointment today for the 23rd of Feb. I'm currently a student at Oxford Uni(have a UK BRP) and want to go for an MBA sports tournament in Paris 8th to 12th May. I can start with spending a few days in Finland if need be but ideally i'd like to just visit Paris. How should i frame my travel plans and cover letter?
