Given sudden job market condition changes, I might be forced to take a Treasury role, dreams of FO over?

Went to a non-target Canadian school for an undergrad in Finance.

Now at Canada's top ranked business school for a Master's in Financial Risk Management at UofT. It finishes in a month and I had done an internship at one of Canada's Big Five for Treasury / Collateral Management as part of the program requirements in-between our semesters. I was given a return offer earlier this week for their Liquidity and Funding Reporting Team (~$90K CAD all in).

They need to know my answer by Friday. I had a round two interview today with one of Canada's Pension Fund's for a Collateral/Securities Lending Analyst Role. As it's on the buy side where I see myself doing PM in the future and longer term starting a HF with some close likeminded friends I would definitely much prefer the PF role. The only problem is if I make it to the final round there's an in-person office visit to meet the team (today's interview was last minute changed to Skype as a result of SARS-2), I sent HR an email later in the afternoon letting them know I had received another offer since the morning's interview and that given the current job environment I would really appreciate it if they could give me an answer as soon as possible. One of my concerns would be getting to the final round which would be after my Thursday deadline and telling the Sell-Side Treasury role I have another offer which lines up better with my career track, but then if the PF interview isn't just a formality to meet the team and make sure the candidate isn't an autist and there's multiple people going to the office that if I get passed up on now I'm fucked.

The other concern is that I was just starting to email more FO contact lists worldwide pulled from Bloomberg, right as everything went underwater and I've been hearing from classmates that existing hiring processes they were in have been cancelled and there's hiring freezes happening for the next 6-12m and people are starting to rationalize taking ~$50,000 CAD roles as a result.

My mind feels so fragmented right now trying to come to the decision of what the optimal way forward is.

I'm thinking if the PF tells me I'll only know after next week I'll have to thank them for everything but that I have to accept another offer for the sake of job security (I have a $150,000 loan to pay-off from undergrad and graduate studies combined). My concern then is career advancement to the buy-side.

TLDR: Is Treasury a dead end to getting somewhere more buy-side and front office oriented and should I try and get an extension on an existing offer from sell side MO which likely expires before I'll know whether I got through the final round for back of the FO on the buy-side?

My reasoning is that the sell-side bank has 50,000+ employees so going from MO to their FO is basically game over unless I went back for an MBA which I don't see myself doing as my undergrad and master's were in relatively pure finance already. Versus at the Pension Fund which is only ~2,000 and there's less politics moving from front of the MO/back of the FO to real FO would be much more straight forward and likely.

Any thoughts whatsoever would be sincerely appreciated. (y)
