This was true for much of the last two decades, but as I say all the time, things are changing:
PSG: Neymar, Mbappé, Buffon, Alves, Cavani, Di María, Verratti
Monaco: Falcao, Jovetić, Chadli, Lopes, Glik
Lyon: Depay, Fekir, Dembélé, Aouar
Marseille: Thauvin, Payet, Gustavo, Strootman
Purely from the stand point of marketing and name recognition I feel Ligue 1 compares favorably to Serie A and the Bundesliga especially.
Compares favorably.. on what front though? Recognisable names is often a sidestep, especially ones like Gigi, Alves, Cavani or Falcao - they will not be here in 2 years and everyone who is well aware of their age knows it's more or less retirement money for them. Unless of course this is a strategy that the league will keep rotating through the years, but also one that assumes the prospects are retained. Getting that balance is what makes you not sink into status of either farmer league who never get anywhere, or the MLS.
What, purely on video production and social media handling standpoint? I'm honestly not the best judge, but I can do some impulse analysis. I won't focus on Serie A much tho.
Beyond lack of availability of English clips and commentary there isn't a whole lot of difference at face value. Ligue 1 presentation on that channel feels somewhat more 'poppy' compared to the Germans, particularly those top10 rankings have a certain celebrity feel with what tracks are used and what images are chosen. And if you're going with original commentary and original French press conferences then at least do subtitles? Serie A channel keeps Italian audio, but puts subtitles, which is the way to do it IMO. French have yet to understand this it seems...
But this isn't really what stands out to the viewer. For me it's a combination of little presentation things you see especially in matches where the league don't put in as much effort to promote relatively mid-to-lower ranked teams i.e. pretty bad lighting with lack of image enhancement. The English in particular have worked this out really well and there are no Premiership grounds that look like you're watching Championship or League One fixture on your TV screen. Italians have this problem too, but for them everything looks naturally "drier and dirtier". The often loose goal nets (which at least to me don't scream 'pro football').. People do not really want to stick to watching the match that looks bad on your screen, they would rather be down there to at least feel the atmosphere if there is one, but not watch poor, greyish, middle-to-lower class looking world. For example:
https://www.youtube.com/watch?v=haEz5RxZ0to - this combination of kits and lack of hue makes it look like there is a layer of dust. Compare this with hue & saturation in Bundesliga clips:
https://www.youtube.com/watch?v=ARjFTDcrYVU - grass looks green not "dirty" green, red is almost always sharp, so is yellow. The little touches such as coloured nets that have become iconic to Bundesliga...
What's the average attendance across Ligue 1? I clicked on Lyon vs Nice which seems like an equivalent of Spurs vs Everton type of fixture and empty seats are quite obvious. The Nimes match against PSG was obviously rammed since it's their first time back in Ligue 1 since Cantona days (is that right? I think I heard it on some podcast, might be wrong). Bundesliga are smart to show mostly matches that have high attendance and make sure to accentuate it in their videos (see Dortmund vs Leipzig).
On the negative side what's quite obvious and annoying about the Bundesliga channel, and what incidentally holds the league back, is that the lower table match highlights are nowhere to be found as you scroll through it (or is it just me?). Seems they're accentuating the top sides and hiding the rest of their shit, which is fairly smart given the level they're at, but most viewers will think to themselves 'hang on a minute...' whenever they find out this league has 20 teams too. Their channel also reminded me why Germans i.e. Leverkusen and Monchengladbach have such a great reputation for online hilarity. Look at the image and sound editing in these:

Amazing mojo of promoting their league that Germans have managed to perfect. Shame it doesn't actually bring regular viewership and is basically just a meme
But what Bundesliga do try and do is appeal to American and East Asian audience, which is fairly clear with their entertainment focus. At least they have some global market targets, whether they're poor from 4th spot down or not. French marketing seems like it's shooting in all directions screaming 'please care about our football, it's not that bad' when in truth they can do simple tweaks to make the TV viewership more pleasant.
But these are just my uninformed impulsive thoughts anyway.
