An Apple TV is compact enough to do the TV connection. Just use AirPlay to connect to it.
One of the larger sub-groups of the Mac User Group used to have a bag of various dongles for presenters to connect to a laser/LED projector. About six years ago they started using an Apple TV 3rd gen connected to the projector via HDMI cable. The audio section is covered by a battery-powered PA system connected to microphones or a 3.5mm audio plug.
This way you don’t have to worry about the limited port selection (Thunderbolt3/USB 4.0) on the current M1 MacBook Air/MacBook Pro.
In truth, I doubt you’d even meed a MacBook Pro: a MacBook Air with 512 GB storage, 16 GB Unified Memory & the 8 graphics cores that comes with that combination should be plenty powerful for you.
I’m basing this recommendation on my base model M1 MacBook Air - that has 256 GB storage, 8 GB Unified Memory & 7 graphics cores. All M1 Macs (except the M1 Pro & Max models) have 8 processor cores.

Neighbours at the other end of the block of units who have set up a snooker table in their garage are playing something weird that’s possibly distantly related to a cross between (c)rap “music” & a demented race-call.

Folk often ask “how long will my Mac last & still be relevant?” Well, I bought my 2017 4k iMac (quad-core 3.0 GHz i5) with a dedicated graphics card & 16 GB RAM just six weeks after that model update was released, July 2017. That’s 5 months shy of five years. It’s still going strong, meeting most of my computing needs & has the newest available OS variant installed. One major change made was exchanging the 1.03 TB Fusion drive with a 1 TB SSD.
If I need more capability or speed, I also have an M1 MacBook Air.

WolframAlpha says I have 23,094 days accumulated…

I was getting that way about the middle of 2018, almost collapsed while interstate at my aunt’s funeral. I was diagnosed as anaemic & needed an iron transfusion 3 weeks later.

It's been a bit of a strange day!
First I found a hat full of money.
Then I was chased by an angry man with a guitar…

Edward Carrington Mack (20 December 1933 – 6 November 2018) was an architect and Australian politician. He is the only person ever to have been elected and re-elected as an independent to local, state, and federal government in Australia, and is often referred to as the "father of the independents.” He chose to serve for only two terms in both the New South Wales state seat of North Shore and the federal seat of North Sydney to avoid receiving a parliamentary pension.

Fun in Australia at the moment is wondering what the federal government is going to fuck up next and vehemently deny they ever said some relevant thing that’s in the public record.
